I have to say, the guns are perfectly balanced, so addition of new ones so soon would be useless...
Also, the mortar is already being developed and guess what - we are gonna have a spotting system (yes, a la CoD).
I do like the idea about this, would add more versatility.
Equipment (<secondary weapon slot?)
1.Grenades (3)
2.Med-kit (would like 2x 50hp, maybe usage on allies)
3.Kevlar (NO!, just NO!!!)
4.Ammo you carry more ammo (<ammo pack? equipment item like med-kit, just 1 use and that on yourself)
Additions
Airstrike on 30 kills (<dont we have such a script on servers? either way, mortar will render this useless)
Sprint on shift (NO!!! everything is fine, the game plays perfectly BF-ish, and making it, well, CoD-ish would make it worse IMHO)
Death-maTch* (<typo :P, but i think that there just might be such a mode on pyspades servers. or something like that, at least)
King of the hill (<we already have a goddamn territorial control mode, one where there is only 1 node to control would seem crowded, to say the least and remain optimistic)
Btw, dont we have, like 10 posts about these same suggestions?
