And I already answered you answer. So let's start over ?
I'm a 0.5 KDA support killstreak player with a MAAWS; the enemy team has a 2.5 KDA guy with a Battle Hind, Helo Pilot assault killstreak.
You say the MAAWS is balanced just 'coz you can die and still get it ? I'm sorry but it doesn't seem balanced for me.
If you put a five kills killstreak that counters dogs it might work-- oh wait! there's one: ballistic vests!!, but it's an eight kills one. So the support counters require more kills just because you can die in between ? 'Coz for me the support line is made so the player can counter the assault one in the nick of time, unless of course the support one is a worse player than the assault one, which would make a lot of sense if you think about it. In other words: for successfully counter an assault killstreak you need to be at least the same gaming skillz level than the assault one, if not better.
If you think in the Specialist killstreak for example: low skillz gamers can use one perk point to get full bonus, skilled ones can use three points ones without issue, so you can adjust it to your skillz level, but to be a support apparently doesn't exempt you from playing at the same skill level of assault ones, which makes me wonder why bother with the persist after death, even tho most of the rewards are just aiders instead of killing stuff.
Back in Blops2, almost all the killstreaks were meant to get you kills, else they were team support ones, which made them very balanced unless you reach the top of them, which created a slaughter fest. In MW3 the support lane let you get support and some kills eventually at a very good decent rate compared with the assault one. But here either way you need not to die or get a lot of kills fast, instead of letting you pick a non-resettable killstreak and have a laid down match.
Since you don't typically equip assault killstreaks that you know you won't get, the 'resets if dies' excuse seems pretty poor for me to increase the costs of the countering killstreaks as there's no balance since you must play as good as the other just to counter him instead of getting an advantage when it comes to the MAAWS specifically.
Could you please give a serious answer plspls ? else I'll just throw you at my "idc 'bout ya!!" list, 'coz you just wont contribute in anything when it comes to me. With regards! ^_^
