An bounty system for stadium would be nice in combination of a little change too, in stadium is it lossible to try players mire than once in a day, which gives me a lot more loses because there are people who just must kill me to make me suffer, which is very annoying, so it would be nice if the "only be able to kill someone once a day" to "only be able to challence someone once a day"|
After that would a bounty system be nice, to get a little payback to someone who kills you daily. To give someome a bounty, he must have hitted you like three/four times in 7 days and that will cost you some resources. When a player got a bounty, he will be showed in a special windowscreen in gamemode stadium, the next five players who kill him gets all 50% of the resources that the player layed in for getting some payback. That will make it worth for players to kill a bounty, and it wont be too expensive(not worth is if just one player can get a reward) for a player to give someone a bounty.
This could make gamemode stadium a lot more interesting, and it helps a lot versus bullies i meet and probably a lot others do.
