You can shoot the turret after you spawn it -- no damage numbers, just eventually breaks. 1 shot from the glaive destroys it, 3 shots from a 180 hand cannon destroys it. Not sure if you can destroy ANY healing turret as you can destroy your own and enemies (in PVP) but I am not sure about your teammate's ones. Also don't know if PvE enemies can destroy it since they don't target it. Because no one other than me seems to use this, it is not that important. Also please buff -- it is so bad. Thanks
