Newbs, thinking they know it better than the experts. Or did he just graduate to the n00b class? Doesn't really matter much though.
Got news for you. Against targets with any serious amount of fortification that monk, that paladin, etc. Probably will do better damage than your average pure DPS toon that suddenly had his damage output cut by more than half by losing their criticals.
Oh and that battle cleric? He's self healing, dealing out melee damage, and probably has both a Blade Barrier AND and Implosion running at the same time if they built the character right.
