I think it'd be pretty cool if when a player is killed, they drop 1-10 gralats coming out of their profile, only able to be picked up by the player who killed them. This would probably not be included inside towers due to high PK traffic, but it'd be cool to see this be implemented, it would increase PKing as well as give players an alternate, but not huge, form of making money. Another idea on this is make a certain "Wager Spar Room", where you pay a certain amount to spar and the winner gets all of the gralats. The combat in this game hasn't changed much aside from the fact that the tournament spar room is now eligible for getting streaks, so this would be a great addition in my opinion.
