The main part of the design I drew up for my Eurogamer Expo custom t-shirt. The whole thing was an appeal for the final profession of Guild Wars 2, which is as yet unknown, to be the mesmer from Guild Wars 1 - I've genericised it for my gallery, but the full text was "Give us the mesmer and nobody gets dominated". Given all the clues and hints they've provided so far, it's a 99.99999% cert to be the mesmer, but as it's my favourite class, I decided to take no chances!
The devs loved it, but they remained tight-lipped! They're way too good at this secrecy business :<
