Silent Crusader, Pride, Angry Dread, and any one-hand Deadly weapons are better choices than SR. At the moment slow OH fist probably the best, as most builds take fist/dagger weaponspec with current itemization. Luckily, you can get one for the cheap cheap price of 50 emblems of heroism from Dalaran vendor.

Edit: After 3.1 patch, of course. Now OH SR is as good as OH CG would be.

Warlocks don't have much way to boost their pet's crit rate. At best, they inherit 30% of the master's through a demonology talent. Hunters can get much higher crit and a much higher attack rate. Note that imps' firebolt is not the spammity spam it used to be. Fully talenting drops it from 2.5 to 2, not from 2 to 1 like it used to. Felguards have a similar attack speed, with infrequent cleaves. It's still an extra group member generating crits, but it's no hunter pet by a far margin.

Is it possible to make a Macro, that uses envenom if you have 4/5 deadly poisons up and eviscerate if less than 4 deadly poisons is up?

No it's not, Blizzard removed the possibility to make "smart macros" like that in the 2.0 patch that came out right before TBC. Basically because the player should make decisions themselves, and not fall back on a bot/macro.

If you want just one button for Eviscerate / Envenom you could make a macro like this:

okay so normal 1 = eviscerate and alt +1 = envenom ?

Been scrolling through lots of pages of HaT and my eyes are blurry now. Anyone state the ideal glyphs to go with for HaT (besides evicerate as that is obvious)

*edit* also assume SnD is the 2nd major

Maybe this question isn’t so simple, and the answer will probably be neither, but here it goes anyway.

Currently we are trying Sartharion + 3 drakes, and we are trying to maximize DPS to get the first drake down as soon as possible.

Before the first drake lands I am able to get a full stack of combo points on Sartharion himself, but I also trigger the cooldowns of 1 or both of my trinkets (I have Mirror Of Truth and Grim Toll at the moment, both of which are trinkets with a proc chance )

My question is what is the best move to do here?

1. Build up the combo points, so that I can have a SnD running straight from the start when engaging the first drake, and not waste energy on that for half of the duration between drake 1 and 2 (5pt SnD last 35 seconds or something like that)
2. Or doing no DPS at Sartharion, and save the proc of the trinkets for the drake fight itself, but having to spend energy on building up combo points for SnD.

Or in other words: trinket procs vs SnD energy.

The problem with Tenebron is, you will have to move as soon as he becomes attackable because of the first lava wave. Your trinket(s) will probably proc within the first ~3 seconds of attacking him, so even though you saved the procs from Sartharion, you won't get the full benefit out of them because it is unlikely you will be able to go full out DPS on Tenebron during the first wave.

I always get 5 CPs on Sarth and TotT the MT in the process, which incidentally also helps with my guilds problem of trigger happy DDs - the few raids where we didn't have a rogue (because I had to tank with an alt) someone almost always pulled aggro, which is an incredibly stupid thing to do, but apparently you get used to giving all you have 1-2 seconds after the pull when you have rogues tricking the MT on every boss.

Since the obvious trinket choices for rogues all have a 45 sec internal cd on procs (correct me if I'm wrong), you will get the proc roughly 15-20 seconds after engaging Tenebron (if you hit Sartharion with TotT as soon as he moved towards the MT after hunter MD), so until Shadron lands you will have enough time to make full use of their effects.

If the fight against Tenebron lasts for more than 45 seconds (which is particularly the case, because shorter fights have enough DPS already) you can have a 2nd trinket proc in the second case.
And the question actually remains the same : will the damage gain of more finishers outweigh the trinket proc loss (even if it is a diminished return)

I think it does, especially if Heroism (which is most of the times launched after 10-15 seconds) is available, which will make your trinket proc of case 1 fall in that heroism timeframe (and giving it an increased value), while the first proc in case 2 will not be in that timeframe.

+ A second proc in case 1 (after about 70s) is not that utopique as well, I guess. (Especially compared to a 3rd proc in case 2 (The Tenebron phase shouldn't last more than 90s))

But I guess we need some maths to prove our point.

IMHO you should not use hero on first drake, save for 2nd one as his aura really hurts. As long as you can kill first without hatching twice you are good. I have no idea about trinket or finishers is better, but the most important during the fight is to have 0 seconds offtarget when drake is attackable. I'm unsure how if trrdr means to move away from the drake with "The problem with Tenebron is, you will have to move as soon as he becomes attackable because of the first lava wave" but you should stay sticked to the drake all the time.
