Lots of traction on this topic, just gonna quickly give my two cents:

Divine shower and Enma's Summons need a cooldown. They are powerful, but they are not broken. What tips them over the edge to me, is their spammability. Enma's especially with HSDW and the Evoker's +30% damage to evocation spells is also a big factor into it. But I can see why divine shower is equally opressive.

I hadn't played the game in about a year and a half, before Korvara. I logged in, fought a hexer, saw them spam enma's and I remember saying:
"WHAT THE HELL, THIS DOESN'T HAVE A COOLDOWN?" I was actually floored at the time.

I think that a two or three turn cooldown would be fine, personally. (Though it'll make grinding annoying! Cooldown for 3 turns if it damages a player? :') )
