Guild Wars 2 does it for me at the moment. I've uninstalled the other mmo's I was playing because GW2 has everything I'm looking for in an mmo.
This brings me to the question, Is there an mmo out on the market that has the same game mechanics and combat system as GW2 ?
If there are any other mmo's that have the game mechanics and combat system of GW2, please share. If not, it's understandable which is why GW2 stands alone as one of the best or the best, in certain opinions, mmo out currently.
