ok, grenade launchers are bugged since the first day...but in patch 13.0 it seemed to add another bug... My GL have to shot every 5 seconds...before 13.0 it shoted every 10 second with very low dmg and after 13.0 my GL shot every seconds and hits every 5-10 seconds...it seems like a fast pistol but with very low dmg...please, engineers like my that took the GL way have a lot of hope in the fix of GLs..please, fix it.
