people that have invis bug abuse breaking the wall but the evi isn't suff because they are invis and it should be removed so all players get banned for breaking the rules just not people who are not invis
So what would give players the ability to not be camped all day at arena? Invis pot is the only reliable protection for non-PVPers in arena. I would instead suggest that the bug itself be fixed or maintained instead of removing a game feature.
Either way, the bug does need to be dealt with somehow so +1
