I have the same problem.

However, I would suggest to everyone that you should take "effectiveness" out of the question. Rather, focus on whether you like the gameplay, and (if this is important to you), the aesthetics.

For me, I love the way paladin plays. It is very slow and methodical and having a fixed rotation gives me freedom to worry about the raid instead.

However, I love the DRK weapon. And I love learning new classes, and right now I suck at DRK.

However, I hate the DRK armor.

However, I'd just like to wield a 2h sword in one hand and a giant shield in the other (D3 Crusader anyone? ^^)...while wearing the awesome PLD AF2.

Oh man =(
