i hope this is sarcastic
It's not.
For example, the brass beast features more damage, but at the cost of slower moving speed (and I think slower starting speed, not sure)
Tomislav has faster wind up time, but fires less bullets.
Cloak and dagger recharges when you're not moving, but you can't go very far when moving at all.
Seems very balanced to me, I don't think Valve could have done a better job at balancing it.
