If there wasnt some magic x10 multiplier that makes fast little dodgy characters the best at it. I mean i get the multiplier for staying alive long enough, but it should go x2 then x4 then x8 in my opinion. The sudden jump to 10x points makes the game optimally played with a shinobi. I cant tell you how many matches Ive won by just playing shinobi, racking up points and altogether avoiding combat. Snag the points then hide with stealth feat.
Use both stamina gain on hit and health gain on hit and you dont have to slow down at all. Hard burn the dash then doubletap two minions and you are ready to dash to the next place.
I like the point capture idea but in this sort of deployment matches are just too quick and too non combative.
