Dominating and vengeful give WAY too many points, especially with multipliers! It's not uncommon for me to score 15/30/45 points for one kill. Rarely I've scored over 100 points when dominating, kill sprees, headshots and multipliers have lined up. This is simply too many points.
Vengeful kills. What the hell is that? If you suck a lot, you get rewarded? Additionally, there's no way to LOSE a vengeful kill as far as I know.. if someone dominates you, you have the entire round to kill them I believe. Whereas, if someone kills you, you have to kill them a whole bunch more for a dominating kill.
Domination/Vengeance should be removed in my opinion. If not, the point bonus needs to be significantly lowered.
