Ammo too scarce?

So like pretty much everyone here, I dove headfirst into the beta with glee. Most of it's pretty good I'd say, though a couple of the weapons for the new perks feel like they could use a small bump in damage. However, that's not what concerns me the most.

So if you have read the patch notes, you should know that Commando and Support had their ammo pools trimmed. This already seems like a poor idea, but it gets worse. Also mentioned is that ammo crates found on the map now only restore a partial magazine's worth of ammo. From what I've seen, it's about 1/5-1/4 of a mag, which is ludicrously low.

But wait, there's more! It seems like the spawn rates for ammo crates, armor, and weapons that drop randomly on the map has been massively reduced.

So to recap: Everyone carries less ammo now, ammo crates are significantly harder to find, and when you do manage to find one, you're awarded with a pittance of ammunition. Even on Hard I find myself running out of ammo quite easily, especially with the new perks.

I feel like this three-pronged attack on our ammo stores was simply too much. I can't see how HoE would even be possible without at least three supports running the ammo backpack skill now.
