You can’t enforce rules in competitive environment, which are impossible to monitor. Thus unfortunately rf rings are what we have to live with. It is sad funcom didn’t nerf them in pvp.
Though everything else, which promotes less equal grounds and can be monitored, should be forbidden. And these things are:
- any kind stat buff potions
- all runes
- any hp potions which is higher tier than (purified) daggamalt
- khitai statues buff
At the start of the match captains of the teams make sure to deliver these rules to members. In case of violation it’s instant match lose. Easy.
