Not every game -needs- to be multiplayer. Introducing PvP means characters must then be "balanced" fairly, which as another poster said means you can't be overpowered even in the single player. Why can't we just have good single player games anymore? They are right, how do you functionally take a game based around killing hordes of mobs and turn those same mechanics into 1v1? The problem is the game was built around PvP being a possibility so that attempt at multiplayer balance is already present, to not have the feature at this point really is unacceptable. They gimped the game for a feature they never delivered.
