My solution is that every marine should be able to place a marker for a structure a little icon would pop up on the comm window and a right click would take the comm to map position of the area also a left click on the icon would automaticly spawn it for building.
I think this is great because if the comm is working with trusted players he wouldnt even need to look and if they arent to sure about the player they can review it for building before commiting team resources.
I think one of the most ackwerd things about commanding is that you cant just click a button to give the requesters health packs, ammo, weapons, upgrades, and even upgrades in structures, instead you must split your attention away from your team moveing to a diffrent part of the map and do these things and if you have a few diffrent squads doing a few diffrent things it can quickly become overwhelming
also since I havent seen a server with more then 32 people ( 16 per team -1 person who is commanding ) it would be nice if each team member were auto assighned a hotkey and you could use shift as you pressed the hotkeys to select more people. there is already a squad hotkey setting you have to set yourself but this would make it easy, also knowing who is in your squad as a soldier and to stick with them would be good too.
Anyways I know I owe mucho respect to anyone who has read the whole thing so thank you
