I think that jmeer presents a good point. Going up against someone with full Prot IV armour and V level weapon enchants is bound to lead to a one sided fight if you don't have the same gear, let alone their MCMMO added on top of that. Although I also want to see MCMMO in the new world, as it'd make things a lot more interesting, the concerning thing is that a lot of people are going to be super overpowered.
