Shandrillar:
I'm new to the game, and loving it thus far. I am still in the "hack" category (I can live with that... I still stink), but I am wondering how one levels up into the amateur status, pro, etc etc.
I can't find any explanations on the levels.
Tiers are "Hack", "Amateur", related to the playing average.
Levels are numbers, 1 to 115 (until now), related to eXperience Points (XPs).
See "Changing Tiers" over there ==>
Explains tiers and - after that - levels.
