I've played this game for 2 years and almost every concept of it seems good to me. The co-op raid is super fun even though it takes a while to find a buddy. There is a certain movement in pvp that causes my characters to move irregularly to the point where I can't vanish. People got good at it and it's really hard to get out of. But I believe that's a show of skill rather than an actual problem with the game so 8 out of 10
