What a ridiculous reply. This is a PvE game with PvP side game.
Why create a PvP expansion when PvP players are an absolute minority in ANY PvE oriented game. You choose not to participate in PvE scenarios, or very little like you said. You can completely opt-out on PvP and not miss a thing.
If you don't do OPS, hardmode FP or PvP what do you do?Then what on earth are you playing this game for? Just storymode fps?
