The multiplier system has it's own (big) flaws too, to be honest. It might use some re-thinking (a brainstorming discussion with the community mb?) , in my opinion.
P.S. Also, i'm in the minority of people who think that a tiny reward for a kill wouldn't hurt at all actually. And don't give me that "people will go apeshit with teamattacks" , it's not like they care about teamattacks now.
