The level 80 gorilla would definitely help. I usually use the method shown in this video:
YouTube - Hunter: Solo Bloodlord Mandokir

Grab the raptor at the start while running up the stairs. You need to make sure that he's aggroed on to you for the entirety of the fight. Since you will be out of his line of sight, he will stand there and evade while targeting you. He does have a threat list however, and keeping up mend pet will out-threat the thunderstomp (if using a gorilla).

When feigning death, he will aggro back onto your pet and will stop evading. You have to unload some damage onto the raptor to get him back on you (he will start evading again when he's on you).

While you're standing out of his line of sight, bloodlord will not Charge or Watch you. The other key is making sure you never rip aggro from your pet. If you do, you will be teleported to Mandokir and feared.

I'm surprised not to see this strategy already here. It may or may not be an unintended bug, but I have not heard anything about an upcoming change to it. I could be wrong.

I'm interested to see if anybody has experimented with a Turtle over Gorilla or Worm in a fight like this one, where there is only one target and absorbing damage is the limiting factor.

No you need a raid to get past the bosses. When I was last time in BWL we left a pack standing and after we cleared I tried to solo them. You essentialy pull the pack onto your gorilla and aoe the goblins that drop the ore, they have little hp, once the goblins are dead you use Feign Death and let your pet die and the pack resets and respawns with new goblins. Loot the dead goblins and repeat.

Intentionally having a mob Evade falls under my definition of exploiting. Creative use of game mechanics is one thing, but using the "Evade" status to take a mob out of the fight amounts to cheating from where I stand.

The raptor has been known to have very screwy behavior throughout the lifecycle of ZG; there was a terrain change and I think a few other tweaks to prevent obvious exploiting, but the basic problems of the Raptor's AI and propensity to Evade were never really fixed. Exploiting this encounter was popular back when it was meaningful content, but doing what you suggest completely undermines the entire point of doing the encounter at level 80.

As previously mentioned in this thread, if you DPS him while swimming in the water, you don't take fall damage from the tossups.

Anybody have any luck with attumen? Don't know if this is at all possible. I'm interested in mounts =D. Just got my deathcharger last night. I haven't gone back to thekal in a while but i've gotten some raid upgrades so far, im not sure if they'll help.

Depending on your specc, gear and resistance, a tenacity pet can offer you:
- a lot more of +aggro (and aoe threat from thunderstomp is a blessing for the whelps)
- more healing received from blood of the rhino (works with both mend pet and 2 pieces tier 5 bonus)
- more survivability for your pet with increased stamina & armor
- more survivability for you with roar of sacrifice (and if specced: intervene)

Without bm specc you will be very thankful for every +aggro you can get you hands on.

Onyxia is not about dps all the time. You will have to md/fd several times during phase 1 & 3. It's all about keeping your serpent up through phase 2, avoid getting hit by too many fireballs and let your pet get all those whelps and properly bomb them quick and deadly.

Especially roar of sacrifice will be crucial for your surviving in phase 2 if you don't want to wear loads of your burning crusade fire resistance gear. Laying down on the ground won't work, without a dot up on the old lady, she will breath (she will do it anyway from time to time) and the breath still hurts for a lot.

Wearing a stamina heavy gear (eg pvp items) might help as good as some fire resistance do, It's really not about dps'ing as fast as you can in the first place.
Before meeting her for the first time, make some preperations. I really recommend a BM specc, some of the biggest healing potins (or use your fire resistance potions from illidan, before they get dusty) and a tenacity pet. A gorilla is preferable due to thunderstomp.

Don't even give it a try with sv specc (hint: she's still fire immun, explosive shot won't hurt her) and not enough experience with the battle and her behaviour, or you might wipe over and over.

I tried to do tiger again. My first attempt went very well but to no avail. All subsequent attempts were not very good... I do it with a worm and i have a spec thats the same as the OP's. Whenever my pet got mortal striked there were some serious problems, mostly resulting in pet death in subsequent attempts. Any suggestions for this? Also, when my pet got stunned and they ran to me, most of the time two of them would stay on me while one went back to my pet. pet had 14k health and 58.05% damage reduction at about 21k armor and i had 17k health and 10k mana.

It is possible to bug out thekal and make him go straight into phase 2. Exploiting a boss like this isn't such a great idea though-- i stumbled upon it myself. He did die though, and he did drop loot (no mount).

anybody else on attumen? i'm guessing it is only done as two-man

I experienced this doing BWL just a few weeks ago. Seven ores dropped, but after the first five I got a message along the lines of "this item cannot be picked up." Very frustrating since several of us were working on getting the ore for finishing the quest chain to open AQ40.

From my experience I only can suggest you taking a ferocity pet. I go with a lvl79 devilsaur and a max pet-build.
During phase 1 & 3 I have to pay attention about aggro, but with just autoshot and a few FDs you shouldn't have any problems, not even with the knockbacks.

During phase 2 I'm just laying around and let my pet do the work. The self-heal through Bloodthirsty and Spirit Bond is more than enough; even if there are 2 or 3 whelps beating on your pet.
Just after the whelp-spawn I stand up, throw a Mend Pet and gain aggro of the whelps to bomb them. After this little action I feign death again and wait till the whelps spawn again (considering my mana in AotDH or AotV).
If I should drop low on health, I just bandage myself to gain aggro of the whelps.

All in all it's a fight of about 10 to 15 minutes and is safely doable without 2T5.

I tried with a lvl80 Gorilladin and had 2 tries, but always got problems with phase 2. Maybe, I should try it once again with my new gained experience.

In order to get into ZG or any other raid instance, you need to be in a raid group. The other person in your raid group CAN be logged out or disconnected.

I usually do one of two things. The first is to join a Wintergrasp raid and then not leave the raid when it is over. 9 out of 10 times, someone in the raid just logs out after WG is over without dropping group, I eventually become the raid leader, and I am free to run ZG. The other thing I do is just ask in general chat or the LFG channel if there is anyone who is about to log out or if there is someone who is just hanging out doing something that doesn't matter if they are in a raid group. Usually I find someone who doesn't mind being invited.
