Yet snipers are important and I can't count how many times I and my team could have used some but no one was or wanted to be one, is that fair then?

I think its stupid that the ONLY thing that gives you big points is base attacking, because certain things like battles and even infantry battles can be important.

On hourglass one time nod said screw fighting the begginning pointless infantry battles in the tunnels, and almost all team gdi came pouring out the tunnels towards the obleisk and a couple of us got through (not me) planted some c4 and boom the obleisk was down in like the first 5 minutes.

Everything has a point, not just attacking the enemy base, yet your rewarded ten fold for attacking the base whether its doing something or not.
