I love the sticky bomb and the uav, but I don’t want to use them in all scenarios. It would be awesome if I could go to the command post and click on the select weapons and have a tab for abilities and switch to what I think is needed for the occasion.
Still can only carry 3 items, but you can remove EMP grenade with UAV in mid game.
That would be great! 
You mean swap out the usable abilities… yeah I could see that being balanced and useful. Good suggestion I feel but I doubt they will work it in.
This would be pretty useful. However, this should only be possible after the cooldown of the skill and currently existing stuff created by the skill should be removed when you change. It should at least be possible to tweak weapons/abilities (put in points that you earned) between maps, since you have some 30 seconds of waiting at the end of the round and pretty much nothing to do.
Yeah I agree if a Medic used adrenaline and switches abilities to use sprint then the adrenaline should quickly be removed.
Same thing with turrets, landmines, caltrops and such.
