Killstreaks in LoL!
Interesting thought I had. What if LoL introduced Killstreaks?!
For example:
5 kills in a row = UAV 7 kills in a row = Free teleport 10 kills in a row = aerial defense drone
These killstreaks would operate similar to Call of Duty. Apples and oranges I know, but the idea of killstreaks is interesting to me!
