@thread title. Yes.
I personally will be leveling hard, as I don't work weekends and I'm on vacation all next week leading up to PAX.
The nice thing about this game is that you can breeze through all the content but still come back to it at any time you want to take it all in, enjoying the content at the level it was intended for, without being an OP god in a world of toddlers and ants.
That said... this will be a short MMO, I would argue, the shortest/smallest AAA release ever. Exception:Tabula Rasa... but does that really count?
I hope to enjoy this game for 3 months... beyond that... I am unsure.
