Don't worry, both myself and several friends who played GW1 to death gave up on it after about 8 months.
It just has no draw after a certain point, leveling is uninspiring and the level cap feels arbitrary, there is literally no end game and PvP is a massive cluster **** with no finesse at all. GW1 was so tight and contained, everything just worked, GW2 just seems....I don't know, kind of sporadic in comparison.
GW1 at least had things to do, the story was mostly compelling throughout the campaigns and gave the progression a real sense of direction, something GW2 lacks in spades. End game GW1 was mostly grinding but the grinding was done in interesting places, UW/FoW/RoT were/are both very fun places to solo/group farm, plus with the addition of Urgoz/Deep/DOA with Factions/Nightfall and then the dungeon journals in EotN there was a plethora of things to do with your time that required people to really work together.
GW2 is just so unfocused, dungeons are a mess because all the classes are so homogenous and combat is just particle effect city, plus the lack of dedicated healers means you either gimp a class into pure utility which is boring as sin or hope everyone is on the ball enough to sort themselves out (which they rarely are), also none of the classes are anywhere near as interesting or rewarding to play as in GW1.
For me GW2 just has none of the charm GW1 won me over with, its just another MMO to me full of needless complexity yet at the same time very little variety, I think they concentrated their efforts in places where they just didn't need to, i.e world scale and graphics when they should have been concentrating on mechanics and filling the world with things to actually do.
Don't get me wrong, I do not think by any means that GW2 is a bad game or a bad MMO, there are a lot of things I really like such as the class active abilities, dynamic events and world bosses, the move active combat style (though it has it's downsides), these are all good things, unfortunately it just doesn't feel like Guild Wars to me, it feels like...well just a good MMO, which just isn't what I wanted from it.
