Nah.
Literally the only difference is that old PvP Servers forced people into PvP who did not want to PvP.
Now you have to PvP with people who want to PvP. (or at least, people who have accepted that risk in exchange for some bonus exp)
I can’t take people who think this isn’t an improvement seriously. Suggesting that the former was better is like suggesting twinks shouldn’t be shoved in their own PvP Bracket. People liked it that way for the same reason - screwing with people who have no chance against you.
