This.
When you spawn, spawn sprinting, and spawn buffing. When you get to the action, THEN you lay down your turret. Since there is no such thing as spawn camping in Brink, you can administer the buff to yourself as you are heading to the action. If you forgot and are almost in/already in battle, then hide and administer it!
BUT, if you have a gatling turret and are in the action...
Gatling Turret > Weapon Buff

How has the gatling turret been working for you? I have the same problem as everyone else. The enemies just walk rigth past my turret an it doesnt shoot at them.
