I agree totally. I also think players who contribute to commander damage should get Contribution points based on their damage ranking in Commander's health, instead of getting contribution points through PVP only. I also suggest that players should share contribution points based on last few players who hit a player instead of the one who kill gets all contribution points only.
So many times we bring a player's health to dying level, he runs away, and someone else gets the contribution points. But in black sun, we share the points when a player dies. This can be used in BOTS too. For example if I damage a player for 90% of his health, I can get 90% of the contribution points when he dies. The player who damage him for 10% gets 10% of the points. But now, the lucky person who gets the last kill gets all the points with just 10% damage! it is not fair.
