Let me stop you there.Orange Knight is the best Arena character in the entire game. No character's RTY has more range than Orange's. Not Green, not Red, not Blue, not anybody.
As for the other characters?
Red is good for Insane, but in Arena his lightning won't work against pros (the people who will juggle you to death).
Blue is a solid character all-around. Everyone knows why.
Green? I don't know why beginners flock to him, but there is honestly nothing there. Once you learn how to play the game at the highest level, he's just not worth using.
This isn't a taste issue. It's simple mechanics. Green Knight is worthless.
well umm yea im all out \ but... were talkin arena and campaign the green has to be unique for some reason and a good one and the green is way better then the orange it does more damage but has less range u culd just easily magic jupm put of the way of a orange RTY so orange sux blue can only use two icsicles for evry full bar so he isnt good unless ur pure str and lightning as u said u can easily juggle him so green knights best hes a pro character he needs parcatice btw were talkin about the four knights not any other chracters but its ok
