I was only averaging about 3,000 support xp per round playing the field ops classes which pales in comparison to the 5 to 10,000 I average with Sawbones or Aura. There would be plenty of times where players would disregard my ammo packs and sit on the crates. I’ve played a couple of matches and have been getting anywhere between to 4 to 8,000 support xp now that there are fewer ammo crates. More emphasis on communication and teamwork is always a good thing in my opinion.
So those ammo crate removal spots
I dunno, ammo support XP is so easy to get… Turn around at spawn and give out ammo directly. XP in the hundreds right off the bat.
They shouldn’t have removed any ammo crates. Relocating is fine, but NOT REMOVING. Playing non-ammo classes in pubs is H O R R I B L E right now. The new rotation has also caused most of the Skyhammers to go Vassili or Rhino and the chances of getting an ammo box are close to none 
By the way, the ammo problem coupled with the new completely unneeded revive animation has made playing Medic nothing but a chore. Awful patch 
I like new changes, makes people more ammo-merc dependant, instead of just camping near conveniently set up unlim ammo box.
Altho new placements are kinda weird, imo, sometimes in the middle of the room. Like it was done in a rush, without much though regarding logistics.
