How about "skills" like:
Hop the reactor (requires basi/mara/goon, or extra fame if done with granger)
Snipe the armory/dc (requires +goon)
Psaw the overmind (requires larmor+psaw)
etc
You see, trem already has Skills/Power Moves
It seems like they're already taking out the need for skill, and putting a huge emphasis on teamwork and which weapon you buy... I realize this isn't CSS and it shouldn't be all about how good your aim is, but it's not "winnie-the-pooh teaches teamwork" either. If you're really fucking skilled, then you should be able to rape people who aren't as skilled.
Skill in using the class, and good aim should still account for something.
Taking out the need for skill? How about the armory hp increase making taking it down require at least a liiiittle bit of skill instead of what 1.1 has...
Aim is not that much of a skill IMO, and can be improved with cheats; dodging, lucijumping, dretching, basi grab, mara hopping, goon pouncing (as movement not attack)/sniping, trample require "skill". Considering that, 1.2 requires a lot more skill since aliens now need secondary attacks more (basi is easier, but imo too few are any good with it in 1.1).
Oh, and teamwork is a skill. A very important one, and even helps in real life.
