Well currently one of the best MMORPGs. The two things that need to change is the battle system, for better mechanics, especially in PvP, and they also need to bring more Open World PvP into the game. Yeah it never meant to be like this, but it has to, so you won't get bored end game after you get all the end game gear. Furthermore it will be more fun and more competitive, as players will get to demonstrate their skills by fighting each other. And with the new patch 4.0 they'll make some changes in the battle system and as we can see so far, they already working on the PvP system and adding it more into the game.
