Bug report: Killstreaks do not stack.
When you earn 2 or more killstreaks of the same type, they won't stack. This means, if I get a satcom, and then get a second satcom before I use first one, I won't be able to use it twice, I'll lose one killstreak. I will be able to place a satcom, not two satcoms.
I believe this could be a programming flaw - they're made as a boolean type variable, instead of integer.
Could be by design, too, but I believe this design is flawed, I don't always have time to place a satcom when I get a 2nd one (I don't always have time to place a vest, and losing one is a painful blow).
In my opinion killstreaks should stack so I can use them several times in a row. What do you think?
