So we have some fly abusers due to the fact that /fly is instant and isn't affected by combat tags. My suggestion is that you have to wait 3 seconds before you can activate /fly if you are out of combat. And if you enter combat it deactivates the /fly therefore making it impossible to /fly abuse and resulting in that all ranks have a chance to win instead of just one guy in /fly coming in with strength 2 and flying away when about to die to eat a gapple.
Any combat activity (whether being the damager or damaged) now deactivates fly. Thank you for bringing this to our attention, you have been credited with $50,000 in-game money.
