I think all is in the Do Not Suggest List

AOS is supposed to be 20th century warfare, without vehicles. Automatic turrets are still not used by armies, except in very few points of the world where you know only enemies may go (Korean DMZ...). And that are completely no-skill weapons. Do you imagine it in maps like Pinpoint ? AOS is not COD and that's good like it. And beside, making it when building would make many players craft the turret by mistake
Sticky grenades were already proposed 50 times. Personly I don't care, a well timed grenade is effective enough
Killstreaks are unfair. This rewards best killers with more kills, making the game boring for Deuces and average players. Imagine the play : 6-killstreak, airstrike on enemy spawn (yes, that's where 90% airstrikes are aimed at), airstrike on enemy spawn... NUKE.
So it's a NO for all your proposals
