I think it would be interesting if each turret has a utility slot that you can specialize in. Each may also slightly alter the turret's appearance. 1) Outdoor drill-base: The turret is no longer just set into the ground, but rather drill into the ground. Allows turret to be setup on more inclined surfaces. Purpose: Ambush 2) Custom coupling base: The turret is mounted onto a custom coupling, instead of straight onto the base. Allows extra turning as well as depression angle. Purpose: Outdoor area defense 3) Range finder attachment: Increase zoom distance by X. Purpose: Outdoor support firing 4) Composite Shield Attachment: Increase HP and adds damage reduction to operator from all direction. Purpose: Indoor defense. And while SOE is at it, I really wish they would just fix the damn turret so it can be placed on slightly uneven area and more terrtain type.
