k im finally buying it this aftern00n. first of all, how much is it worth? in euros if its possible plz ;).
then, ive been checking some things and.. whats a mesmer? i looked at dictionaries but couldnt find the meaning. any hint or clue?
last of all, what class do u recommend me? i love wizs and etc, so i thought elementalist would be pretty good, but i accept recommendation.

mesmer = class that mesmerizes (look up Franz Mesmer)
