What would be better is if we made them for support instead of the other killstreaks
I'm not sure to understand what you mean, can you explain me more please.
Also, i found a way to put, instead of the 3 first perks you need to select, to put assault killstreak.
That mean that at seven kills, i unlock every perks, put i still can run and call my assault killstreak like if i was on assault!
Even better, when you have assault killstreak on specialist, you don't need to call them, for exemple, when i unlock the ''dog killstreak'' instead of having to call him, he spawn directly behind me at the second I get the kill to unlock it. Same thing with other killstreak.
And what is really awsome with this new way is that in the enemy killcam, they won't see you have all the perks.
So less peoples yelling at activision about all perks glitch = less chance of this new way get patched again !
Last thing, i also, if you don't want to run assault or support killstreak with this method, found a way, if you select in first the the 3 bigger perks, you would be suppost to unlock the ''all perks'' only after 16 kills, but you can edit it and stilll unlock each 3 perks after 1 kill for each and then unlock the ''all perks'' at 7kills instead of 16 !
