I would not trust most places to find stats. Btw you got Vippered, jk . Anyway, all the good usf players know the mortar is a fuking trap. 1 may be used to clear a small garrison, but that is about it. You are far better off stalling for the mortar halftrack or pak Howie. Next patch, you will be better off using Soviets. Punish the silly spammers with a couple of snipers or clown cars.
Mortar is sadly basically required in 2v2s and on some 1v1 maps with great MG garrison positions. It's that or tech for nades early, and that's not really a realistic option in the early game.
The Mortar HT is way better but conversely is never seen in 1v1 because it's fuel that isn't going towards rushing tanks onto the field lol
I really don't know what people see in the Pack howitzer. Even before this scatter nerf I basically only ever used it or saw it used versus the OKW trucks, or on really small 1v1 maps where it could deny a VP without too much danger to itself. The projectile is ungodly slow and it can't provide smoke like the mortar can (WP requires vet, munitions, and is far worse for concealment purposes). I understand the meta may have been different in team games, but I never played those. I have no idea how the update is going to affect its performance there, but in 1v1 it seems an even more unreliable option to take now.
I wish we could just bite the bullet and - if we are going to consider this unit OP for it's autoattack - rework this unit completely so it is a barrage-only unit with a much shorter barrage recharge time (maybe 30s?), much faster projectiles, and maybe some more shells per barrage. That or a long-recharge high damage barrage to make it the rocket artillery analogue for USF.
As it is I have a sinking suspicion the nerf to AA scatter isn't going to stop the complaints about this unit, and so the trend, for now, is turning this thing slowly and slowly more into an extremely expensive and basically ineffective mortar - to complement the cheap and ineffective t0 mortar, though at least that can provide free smoke.
