Well since you all were engaged in

LEWT DeWD3 ub3R talkin... look down at your shoes, and notice there tied together, where is your coin purse? Why is your maiden smiling so ravenshely as if fresh from a romance? Give chase my friend? I think not, for to follow the shadow is your folly, for the dark can be a dangerous place. Who are we you ask? We are the rogues.
Of course that is my humble opion
Best character for me is Fighter/Thief--duel class human. I switched his animation from fighter to Thief, and pretty much have a blast with him.
As far as weapons there are not realy any best weapon, it more like best weapon for the situation. Example is that there are some mean critters out there that take a certain type of weapon to hit them, and if your not trained into that weapon or don't have that type of weapon you could be hurting (or have to go and re-equip).
Best character? One that is your play style. Don't try and be a rogue if you want a fighter, don't be a mage if you want a fighter, don't be a fighter if you want to cast, etc. etc...
