1. Bug: You can not spawn more turrets (can not activate armor skill) if there are 3 turrets already.
Expected: You can spawn a new turret (activate armor skill) any time it is off CD and has enough focus, but destroys the oldest turret if there are 3 already.
2. Bug: Turrets bug out and do not despawn (self destruct) after 60 seconds, in combo with (1.) this will effectively prevent you from using the armor still alltogether.
