Not to be debbie downer either but the buzz around the Crusader class wasn't very good in beta. Supposedly very slow and underpowered compared to other classes. Some of their loot seems to have the 1.0 design mentality too "remove X crappy downside from Y ability" instead of doing something really cool.
I'll be anxious to hear what people here think of them once they get into Torment. After playing a Wizard it is really hard to play anything else, they are just too damned good.
Playing: Xenoblade Chronicles DE, Ys IX, God of War
Watching: Lupin, You me and the Apocalypse, Days of Thunder
