It sounds like it is. The best shotguns were the problem. So every single special got nerfed... Yet the nerf also hits the worse specials the worst. Would you want to use pocket infinity now? Just wondering...
I haven't tried yet, but all these nerfs combined:
Only 3-5 crates per map.
25% per use, 2 minute respawn.
Takes 4 crate uses, 8 minutes for full special ammo using 1 crate.
EDIT: Special ammo crates now have a 100m drop radius ( so basically the whole map)
If your teammate takes the crate, you have 20 seconds to pick up the drop or it will despawn (120s resp inc)

Again, this further reinforces the idea of holding onto your ammo more than spamming away with it. Pocket infinity was one the fusion rifles that always kicked my ass and now it's going to be cut back too (though the fusion nerf already did that)
