How many times I made builds for throwers , xbowmen , archers , cavs , ... and getting annoyed by few wpf missing or a low melee profiency ?
Then, I think a conversion of skills points would be a pretty cool way to hybridize ranged classes , and then, remove the "full bow/xbow/throwing" chars
If 1 skill point -> 25 weapon points, that would be useless to maximise again the main fighting skill (bow/xbow/ ...) and that would encourage archers and other classes to fight at melee.
