Personally i stopped playing GW2 after 1,5-2 months its more then SW:TOR :P so thats a plus but for me while the game was okay. It did to me not provide the PVP i expected, i got somehow bored of SPVP almost instantly in a week of doing it which saddened me. And while WvWvW at the end was the only thing that kept me playing i somehow one day decided not to play and ever since have not played it again.
Its a good game overall, just to me couldnt grab me. I personally need something to want to work towards and that was something gw2 did not provide. While it might be a bad mindset i just cant be *peeped* if i don't get stronger by getting new and more rare/better gear.
While the pvp part everybody same level / fair playing ground is great to me that does not work at all in PVE. Besides this problem the PVE content which i still do not consider to include questing or the lower level open world zones just did not grip me either. I disliked the story weirdly integrated into the quest and the fact for most stuff in a zone i needed to talk with a NPC to be told in about 30 seconds what the zone was about.
All of this is personal preferences most coming from playing wow / swtor / rift. In the end it was not a bad game at all. It just was not something me or most of the guild seemed to enjoy.
