So the Auto Sentry Turret alone is a very weak Armor Ability but when used together it is a VERY helpful tool that can be used to control routes of travel and positions of power. It also can affect the Aim Assist of the enemy as well as distracting them and forcing them to use up valuable ammo destroying the turret.
Lastly, and most importantly, the turret does real damage to the enemy. Its not a lot but this, in conjunction with the above means that its one hell of an AA, especially when used in tandem with other turrets.
Tell me what you think of this. It can be countered with Holograms, Invis, destruction of the turret, and pulse grenades (when used effectively).
