You would need to pull alot more than 50 mobs in pofire, and have multiple shakers.
I think the biggest reason bluebies called for the nerf to ES pulls is because of common misconceptions about them.
Firstly, the reward is great, but no where near some estimates I hear from bluebie. The best ES pull I ever pulled on my warrior, I was ungrouped, had my shaman box slow and puma me, popped my lesson and ES'd every mob in pov for 18aa's in 1 pull.
In a group, all group members get anywhere from 1-3aa's per pull, depending on the amount of mobs that die. 99.9999% you dont kill most of the mobs and die at the end.
I was in a bluebie general chat and some dude was like "haha now warriors can't es 30 aas every 20 minutes anymore"... well first off we can only do it every 40 mins.
Also, you can't even get good AAs or exp after 70, there are just no zones where esing is plausible after that. So whats the problem?
In order to pull of you need to spec your warriors AA's to es'ing. Your first 200-250 aa's are going to so you can stop pulling poinnovation and move onto povalor or dranik hallows. And innovation is shitty exp.
Not to mention the amount of skill needed to pull one off, the set up of an enchanter or shaman to slow you, etc. its retarded that after 4 years of warriors having a quirky little trick that so few could do and/or pull of they decide to ninja-nerf it like this.
I just dont understand why bluebies are rejoicing over this, i dont see how it affected their gameplay. Everyone on zek is pissed cuz we hate killing mobs designed to be defeated etc. its why we are so far behind in progression we just like fightin eachother.
my theory to why the sudden nerf: maybe there is some content in the new expansion they dont want warriors to es
