Well, I like to get more and more and sometimes they can show whether you're good or not (Xiahou got 1000 kills two months or so before me ).
But overall, I wouldn't try really hard to get them, just sometimes I thought "hey, why not play a medic to get some points for that medic achievement?" so they can be useful if well-implemented.

I never bothered to look for some dwarf in episode two though, never seen any either.
