I'm VERY surprised how stable everything seems. Had a little downtime this afternoon and the auction houses have been down. It's running very smooth for me otherwise. Nice atmosphere, the WvWvW thing is really a lot of fun, and I'm not a PvP'er. I really don't understand exactly what I'm doing there quite yet but you can figure out how to be helpful when getting started at least.
Made a Charr warrior first... I like him but I really wanted to try something different from the 'ole WoW days so I made a Asure mesmer. Lots of fun so far! I'm going to probably do an engineer next.
And one more thing, I find myself playing and not paying any attention to my level or even really loot. The world just seems to suck you in and pull you along so you don't really even care if you're level 4 or 10. I like that. I also am enjoying exploring again. I generally really like crafting but I just haven't really looked at that yet.
Will I play for 7 years like I did WoW? No idea. Will I get my $60 out of it? Oh yes.
