im not sure if this is breaking the rules or not but every time i go to fight using pots i get healed, which removes the potion effect. This is used by many donators and if this isn't against the rules i think it should be considered. UnlcleUrnesto - is one of the users that abuse this feature. Also i have added an image to show that he healed me.
I'm really sorry, but there is no rule against using /heal *. You can make a suggestion to take the command down if you wish. But since this player didn't break any rules-
