I think a simple feature that would give everyone some warm fuzzy would be making tower kill credit work the same as Champion kill credit.

I cant even count the number of times Ive been smashing a tower just to have a minion take the last hit and credit for dropping the tower.

If you are fighting a champion, and a minion or turret get the last hit you still get credit for the kill, which is reflected in your stats. I think this is how killing a turret should work.

Thanks for reading =D
