Maybe a unpopular opinion but i do not think WoW is a great game.
It was revolutionary at the time it came out and it deserves to be a classic.
But these days it is just bad nostalgia and like most subscription games just holds you hostage. Have not played in a long time, since i noticed many antisocial mechanics that other MMOs just do better.
Then again i hate gear grind so i prefer gw2 for that reason alone.
