that person, the one who can spout of stats about your class or game mechanics. Although, in the beginning, I rolled my eyes at people who pondered the math of the game, today finds me holding a deep respect for you number junkies. You've all helped many of us become uncrushable, uncrittable and even understand how +spell damage and +healing work.

(I rarely have the inclination to work the numbers myself.)
