I have noticed at least two players on the opposing team and at lest one of my own team members deploying what I feel is an innaproprate action. Basically I or a teammate are shooting at a player and have their health down to near-death levels and then they self-destruct. Not just once, but almost every time you have them near death. I feel that this is not an approprate action for players to be performing as nobody gets the points for their death.
I suggest you apply limitations to self-destructing. If they recieved damage in the last twenty seconds, they should be blocked from performing this action. I would also suggest that self destructing distribute an assist kill to anyone who has dealt 80% of the damage to their armor.
