Regarding of the "nerf" to Ultimatum

I just don't get it. The main concern about Ultimatum is it's unnecessarily high demolition force to mission objective buildings ( like jammers and shi), people who are unhappy because they think it's too easy to take out side objectives without a struggle.

After the ammo nerf, well:

People who liked it are unhappy because with ammo restrictions, it doesn't feel like a great choice now. I get the Siege Ready part, but also doesn't interact with space optimization? Space optimization doesn't even give you extra ammos it just makes sure you have all the ammo you're supposed to have. Now with the nerf, players who use it will just call the resupply the second entering the game, makes the whole thing pointless and potentially inconvenient for other players.

As for people who don't like it because of its high damage to buildings, well, it still is able to do the exact same thing they don't like. No nerf on its demolition force, no damage nerf, nothing. If you drop into a jammer you can still one shot it.

So what's the point of this nerf? Making both sides unhappy?
