Ok, after running 30+ hm flashpoints and seeing only 1 time (yes, 1 time) a token drop for my class (bounty hunter) and realizing that some of my npc companions have from 2 to 3 columi set pieces that i won on greed rolls because nobody on the party wanting them i decided to leave a suggestion...
Maybe instead of having 4 tokens, 1 per class, how about merging 2 classes for the flashpoint tokens? For example, having a sith warrior/inquisitor token and a agent/bh token. Because, to be honest, I'd rather be losing need rolls against other players than never seeing my class token drop...
