Starting off infantry weapons are fine, although I can see why some don't like the iron sights you have to go through to get a scope\red dot\halo. Also if I'm playing on a server with lots of high ranks and the next map is grand bazaar, I'll normally leave after a couple of mins. It just gets full of USAS and frag ammo, which is no fun if you don't have one 
I haven't bothered playing jets, but it does seem that is where the main issues lie when starting off? It does sound unbalanced anyway.
