The game was very bugged and did plenty of rollbacks too, not a thing MMO players enjoy having their progress erased, also plenty of exploits on a PvP focused endgame like a guild could just report every player on the other side and they would be auto-kicked from the game. Also the game was very light on content precisely because they pivoted from hardcore PvP to a more PvE friendly thing in the middle of development, pleasing almost no one from either side.
