Yeah, I totally am. I'm a sword-and-shield knight, but adding a crossbow to my arsenal would be deadly.
My main character is like this (but two handed). I'm going to use the crossbow to pick off the first guy as i move in and then switch back to my normal weapons.
With my archer, he's still a fairly low level, so i'm holding off training him up. I'll let him get a crossbow first and he can train up properly with that.
