Woah, I'm glad that beta weekend is over otherwise I would never have started on studying for my mid-terms. Sorry I never really got to play with you guys, i was mostly just solo'ing PvE because 1) I felt as if I had no idea what I was doing and wanted to learn from the beginning first and 2) My gaming "rig" right now is an old laptop as my desktop has sadly bit the dust. So until I build myself another gaming computer the sheer drop in framerate that I experienced in the big WvW areas is enough to push away for now, and I was unable to get in contact with most of my GW1 friends so 5v5 structured never happened. I have to say though I'm extremely impressed by the PvE, as in I have never played anything as good as what A.net has made for this game. Soling was actually fun, as there was always something going on (no real quests, just dynamic events and rewards for killing creatures). I'm still a little skeptical about PvP, as I was a huge fan of GvG from GW1 which they've basically scrapped, and while I have no problem with a 5v5 capture point style game, I really hope they add something else or that's going to get really boring fast and WvW may be fun, but it is lacking any form of structure from what I saw.
Tl;dr Beta weekend is awesome, and GW2 is really fun, though A.net needs to listen more to their PvP community.
