I like it in short bursts but it's very daunting when you know how far behind you really are. You feel like you can never catch up and it makes me want to log off and go back to playing WoW. There aren't as many vast resources like WoW has for explaining how to play your character when you're 4 years behind, what stats to look out for, how to optimize yourself etc... Leveling is slow and boring when you're totally alone and I feel VERY alone and in a vast mmo like GW2, it's not a good feeling. It doesn't make you feel like you're in a single player game it just makes you feel like a single person in an empty place.
