The post was edited as I changed my mind a bit about crusader since writing this post. First sentence of this post sums up my opinion pretty well. This build was called "OP Crusader build", well, that was exaggeration - I thought this build is amazing as I played with very undergeared people with 2 - 3x less paper damage than me and no elemental bonuses. When I found guys around my damage, I found out that even with this build Crusader is way underpowered. This build is good for AOE (as long as you have 3-4 monsters close, its good), but poor for single target. You need CDR.
