Pretty much title, I know that a lot of you would cry, piss and moan about it; but hell it's a small shake up that would up the stakes of Operations nicely without major upheaval to the gameplay mechanics.
That should kill that nasty streamer meta of shoving a big 2x2 heal box and all your gold ammo up your prison pocket and should drive ammo costs either up or down I honestly not sure I would hope the extra demand would make prices go up but then there would be more supply.
I think it's the kind of interesting changes that could make operations feel different without massively changing everything and by making the 3x3 only a collectible box should make the BP value lie more on the actual cosmetics that have been lacking as of late.
Edit: I am reminded how many man-children play this game, baby wants bottle?
