I completely agree with you. I used to love gw1 so, so much. I played it up to the very last day.
For me, I loved the game mechanics, which are completely and utterly different in gw2, also the sense of community. Everyday i used to run UW with my guild and used to have so much fun. Dungeons in gw2 are so time consuming and are so different. I wish gw2 had never come out and they just kept gw1 going.
