I popped into WvW for a short while on Saturday morning, at the point where Kodash was pretty much raping everything in sight.
Keeping in mind that I was still running around in level 2 gear (I hopped in right after creating my character), I had a pretty good run. Someone said somewhere Ele air skills lack punch - I figure the couple of Kodash invaders I went after will disagree - I managed to finish them off in short order.
WvW will probably see a little bit more of me after launch - I don't see that STI will be actively involved in it all that much, but I might try and scratch together a group from time to time to run with the INI and PING guys. I did see a couple of you running around on Saturday
