On a side note, it is not at all unusual for MMOs to dip below 60 fps in heavily populated areas even on the most high end systems. Usually in cities and such - such areas are usually processor bound and the GPU doesn't help much in very densely populated areas. Even in WoW, I can dip to 30 fps at ultra settings, 1600p, in orgrimmar in front of the auction house when hundreds of players are around me. I played on the illidan realm which is probably the most populated realm in the US.
I really enjoy Guild Wars 2, although it does seem more like a conventional MMO than I would like. I feel like MMOs need to be shaken up - developers need to think out of the box! I'm sick of WoW clones. It has some good ideas, is very well polished, but it does stick to a lot of conventional ideas as well.
I would hardly call it a conventional game. Dynamic Events and the Heart system are more fluid than the standard talk to someone and retrieve or kill something. The jumping puzzles make for some interesting events. Have you found the vista in Lion's Arch where you follow the dead pirate captain? I haven't seen anything like that in an MMO before. The World vs World system may be large scale PvP, but with a bit added to it like supply lines.
