i switched from my old tal rasha to a crit tal rasha a week ago. i noticed i was dying more often than i used to while fighting reflects. it was weird, but still ok, since i don't die much anyways, so i just ignored it.
a couple of days ago i decided to switch my soundrel to templar just for fun. i noticed i am back to where i was before the ammy switch and rarely die killing myself with reflects.
what i realized is that you will more likely to kill yourself when you have too much dps vs defensive stats even if you have a high ls; and there is breaking point for the balance of dps vs defence, for me, it's the extra 4% cc.
crit isn't always king, it needs to be balanced with defensive stats, i.e. armor, ar and vit.
