I don't mind the set up with the scout class at all, or the amount that play as scout in a game. But I think that there are loads on BF that hates it big time.
But the big question is that, if you could remove the sweet spot and the ADS bit of magic. What are you willing to give up on your classes.
Assault - no more tank frags.
Medic - bring the dead back to life - if your head is no more you are dead etc.
Support - no more running about with easy, with a lmg.
The above is just one or two crazy ideas at 11.00 o'clock at night, so just make light heart of it please.
