Coil turn 1/2? I'm sorry what did you expect WoW-esque LFR where 6 out of 25 people could be afk, another 6 dead, another 6 incompetent and still clear everything flawlessly in an hour?

I have played WoW, I have played XIV, I have played ToR, I have played Rift, and in not ONE of those games has the endgame been "problematic" for the reasons you state, I suggest you find more skilled players to play with, or reexamine your own skill level as thusfar I've yet to hear anyone else describe Coil turns 1/2 as "difficult" or "Challenging".

AK? Ifrit HM? "Difficulty"? I'm sorry but what difficulty? Both of those fights are nearly impossible to fail, I'm fairly sure you can stand in >50% of the mechanics in both of those and not die...sorry maybe you should go back to doing LFR in WoW.
