you're right, it is a while back. but i believe that 08-09 had player weapons, not player roles. weapons ranked the highest rated attributes to the lowest in the allowed rating range (usually from 91-99 and some weapons started in the upper 80s).
but since i been on my ps3 since it came out, i can't really play last-gen games. but the other day i thought i saw that 08 still have player roles or something like that, and maybe that's what you're talking about. i'm not completely sure on this, it could've been a dream lol
