No support, the clash of swords is scarring my cows XD jk. Let skyblock be a relatively peaceful server, there is no point in a pvp arena when there are so many game modes for pvp. I can already see the spam "ban X he is using bowhack", " Y cheats he has aimbot", " you noob Z you have kill aura give me back my stuff" or "W has anti knockback report him". No thanks, spill your guts somewhere else please. Skyblock is for builders, if you dont have anything to build don't waste our bandwidth.
No support. Though I do not play skyblock, the pvp would be far too OP for donors. Ex: Titans have /fly and /god, an Overpowered kit, and /god.
Well in the arena it is possible to make /god disabled. Not remove /enchant, it is a titan perk. Maybe make it so it cant be like sharp5, p5 or power 5. Nerf, not remove. Lol your signature....
