I definitely plan on carrying a couple characters from Guild Wars into GW2. Valion and Volsak are my current choices, but I may remake a couple more as Human. The two will be my main human characters of Krytan and Ascalonian descent respectively. A Mesmer could come about eventually; assuming that it does reboot.
Maaaaybe I'd make an Asuran character. Just maybe. I really don't appreciate the "cuteness" of the race, but summoning golems would be tight. College of choice: Synergetics.
