Some thing comes in mind after few matches

[BeezOne84]

 - Specify icons for mortar, tank and field artillery kills instead of simple skull

 - Add knocked down icon because sometimes it looks like I'm already dead and watching it in spectator mode

 - Last buy button at buy menu so players could easily buy same things as before! Or possibility to save loadouts.

 - additional 25-30% boosters for max health/cevlar/ammo/god knows (only one at time) 

 - squad members list with class icons right under spawn list (i.e. leader and flags) so players don't need to check present classes in Squad management

 - Suppressed versions of some guns which is not reveal you on mini-map

 - Carbine or SMG for sapper. Shotgun only, really? It's useless at 30m and higher!

 - Some kind of accessory (or simply accurate but not very lethal weapon) for recon which is marks target player when hits with glowing silhouette for a moment (5 seconds at max). It could be a balanced decision instead of 3d spotting by some key on keyboard (if you ever going to implement this).
