Nah, I mentioned heavensward. I was in Aery on my Warrior. The healer made me die twice and I did say I was doing big pulls, mhm. I figured they could not handle it after, therefore I decided to do baby pulls. Don't know why they got mad at me when they said ok. It is odd. Again, I popped CDs so I probably shouldn't have died.
There are big pulls and there are intelligent big pulls. I know this is heresy to say, but it also goes into what mobs are in these big pulls. In the Aery, for example, everyone grabs the two (three) aoe drakes with the big dragon before the two sleeping dragons back to back room.
There are multiple aoes going off and that pull is already kind of annoying as is. Some tanks pull the dragonbro before that into the pack as well, which makes it harder to handle. If someone grabbed the three baby dragons before that guy into that pull, that could get overwhelming pretty fast especially if you accidentally stand in an aoe just once.
Also as a tank there's more you can do to help a pull than think that your cooldowns will save you from having to know how to position yourself and mobs and using your skills in a decent way. In the end these are still level synced dungeons and while they're not that difficult persay, there are definitely ways to really fuck yourself or your group over with how you approach the pulls.
Just remember that a pull with many mobs is likely going to last longer than Vengeance's timer. If a majority of the adds are still up and vengeance/raw intuition are down, then you need to improvise and start using other things.
Also pulling large packs of mobs and relying on Raw Intuition, for example, before you have Awareness... You're going to get straight up murdered
because of popping Raw Intuition.
