Welcome!
Considering that you've played for two years (regardless of whether or not you've played a Mage) and you wanna 'start fresh,' might as well pick Trickster. It's new, it's fresh
lololol. But then since you plan on 'maxing it out,' you'll have to consider the fact that mages really become more and more powerful especially in the higher levels.
But then again, you might be among the first to play a trickster up to the top and who knows, it might be fun and sick. Well it should be, lol
Note: I haven't played on OS in ages so that wall of text is just my opinion.
