A loadout i would make for an AK is Drakes AK (blindfire might help for ambushes), a Para 9 with blindfire(also helps in ambush, and its good to have an automatic and semi automatic) Booster 1: Regeneration (if you're running away from being shot at) Booster 2: Daredevil (so you dont have a problem with losing ammo. Level 2 will also give you a grenade so if you're ambushed, you may be able to get a grenade kill) And for the Kickback, SmokeBomb. If you want to survive an ambush, Smoke Bomb will help a lot, as long as you can press the Up button fast enough (i'm sure you are)
Come on the minor Blindfire boost with Drakes AK is next to useless.
Marlowe's Para is great if you want to blindfire a para.
As for loadouts Team Safe is by far the best slot 1 booster imo.
Slot 2 boosters i'd use are Monkey Man or Regen (even though it's broken because of lag)
Daredevil is good if you're using Quickboom otherwise its kinda meh.
As for smokeBomb never used it so can't comment but I will say it's not very reliable.
