Kill streak bonuses

[SCorpA1]

you all know there are now bonuses for killstreaks (like kill 10 tanks without dying)
and i dont want to see gold bonuses.
the idea is, that you get an ability or something else (you can use it only once) to call an artellery strike or orbital strike or something diffrent if you kill e.g. 10 players in a row.
just like in cod
here are some examples:
5 kills streak: troopbonus or troopspawn for a minute or special creep spawn at the base
10 kills streak: supply drop:drops a little box at tagret area which transforms to a little fac for 1min, then it explodes or similar
15 kills streak: you can call one artellery strike at a specific position with 1000 aoe and a delay by 10secs
etc etc

its not gold bonus, but it gives some tactical advantages
