First coil is already pretty much trivialized at this point. (Don't have to do slime feeding in Turn 1 due to echo, Enrage Turn 2, Turn 3 is ezpz, Turn 4 mobs die super quickly due to echo, conflag and dreadknights are easy to kill in Turn 5 due to echo, tanks are much easier to keep alive due to echo...etc.)

Heck, there have been 4-man clears of Turn 5.
