This was kinda how the old system were. It would be weird to go the other way again.
This kind of idea would actually help me alot, but as much as i would like it, just because of the amount kills i get. U gotta face that this will cause alot of teamkills, people will go berserk for the extra gold/xp. And i wouldent like that at all. I find the teamhits bad enough as it is atm.
PS: we alrdy have valor as anal bleeding said. It doesnt work perfectly, but i would rather keep it at that.
