I spoke to these two guys from Wartower for quite a while at the NCSoft party and they are seriously funny.
After so much speculation about mesmer being the final profession I really doubt it will be. Can you imagine if they said it was? People would just say "we knew months ago, big deal" It's been drawn out too long so I'm expecting something less obvious.
*Martin Kerstein And the guys from Wartower are genius. Klaus (4thVariety) has a whole list of small clues or grounded speculation. Didn't expect them to come up with a sketch like this one though!
