I actually dps this fight in bear form wearing a very high expertise threat set. Since I'm already wearing the gear and in bear form, I tank the adds when the arm dies as well. I've consistently gotten top 10 dps with a couple attempts into top 5 this way standing just in front of his right shoulder. Rage is a minor issue but if you are good about managing your mauls against your rage, you shouldn't have an issue. Threat isn't an issue since we dps the right arm first until it dies and then switch back to it every time it respawns.

The (level-based) mechanics have been changed back in 3.0 - in a way, however, that left glancing rates and damage depression the same for bosses, so it went largely unnoticed (see this post and following).

I've tried in both 10 and 25 to get behind the Right Arm, each to no avail. I actually went high Haste consumables/extra gear pieces and high Expertise and ended up hitting top 7 or so DPS anyway. Worked well with all the ArP I've got. You end up with a stupid amount of Clearcasts, but you can get in a billion Ferocious Bites. Overall, ~25% DPS loss from what I hit normally.

I'm getting similar errors to Kologarn's arms on the Heart of the Deconstructor, in terms of being able to get behind it. I get Target must be in front of you errors when I move opposite where I get You must be behind your target errors from Shred. It seems to vary from attempt to attempt, and is incredibly frustrating. Any suggestions?

The trick with the heart is it's a lot bigger than it looks. If you're at max range back on the boss, you should be able to shred the heart. If you're getting errors, back up.

Yeah, the heart hitbox is massive. Hunters occationally have to back up to range it as well, so backing up is the solution.

Also on Kolgarn, each arm shares the same location and size hitbox of the body, so you can hit either arm from any position, including hitting the right arm while directly under the left arm. Using this to spread out across the front of Kolgarn is a great way to keep melee alive and avoid over stacking for eyebeams.

a simple question in between... due to our lack of damage I've been forced from our guild to take cat spec as second spec to my bear spec. and due to the fact, that heal isn't really that satisfying for me anymore since 3.1... I don't regret.

the question is now... i've planned to hit something like 4,5k dps (if more, no problem) - especially at xt-002 25man - so... how many dps should I do completely unbuffed at the lvl83 training dummy?
I know, I have to optimize my rotation a bit and I have to learn to use things like trinkets and Tiger's Fury properly, but I recently did 2,5k dps fully buffed with bear spec and bear gear in cat form yesterday - so I think with cat spec and cat gear in cat form my actual 2,3k dps fully unbuffed are not so bad at all. But is there any kinda number, where I should aim for at the training dummy, so I can say "4,5k+ dps are within the realms of possibility"?

oh, and btw: if you check my armory you see my actual kitty equipment which isn't optimal at this point. too much hit, lack of enchants etc... maybe you take this into consideration, if you're trying to give me advices

@dmw: Download RAWR, turn off all buffs/debuffs and you will see how much DPS you should hit on the target dummy.

Something like 3500 DPS should be your aim I guess, but RAWR will tell you....

Managing about 3620 dps vs 83TD with motw, no other buffs or debuffs.

Rawr says 4272 but i dont see that happening - where can a 600dps shortfall be coming from, thats huge.

How much of your theoretical unbuffed dps is realistic to expect against a target dummy?

The heart of XT was shredable all the time we spent on this boss - for me. Also there are not mechanics, which should force boss to turn back... maybe black hole pulled MT before droping heart. If BliZz didnt chaged this encounter from our kill, you should be abble to run around and find shredable position. But as I reported, if you are staying behind boss all the possible time, you should be able from this position shred heart all the time it drops.

For Kologarn, Im prety sure, there are no position for using shred. The boss is unchargable for warr - I didnt tryed, but it should be unchargable for feral cat. Very probably, because his back is not accesable. I just have to spam mangle (not improved) and pushed 5300 DPS, was second in or guild, behind shadow priest, who was abble to AoE arm elementals. I dont know, how much you lose by mangling. I did 200 more DPS on Ignis without being potted (no haste), but its hard to compare, because Ignis is retaded still turning boos.
On Kologarn, there is also interesting to AoE both arms and boos. Just buff the SR and spam swipe. I didnt tryed... just interested in how much DPS provide swiping 3 targets?
