Remember that you're not forced to use the full Battalions, so if you can afford at least half of them and don't mind the extra micromanagement it's actually more of a bonus than a downside.
-Have hard targets that are attacked by AT guns use their against-infantry HP
You seem to be misunderstanding how this works (which is normal, as it's not easy to find out.)
Your suggestion would probably be hard to implement because High Velocity Guns are "hard weapons", whether mounted on an actual tank or on an AT gun chassis.
(AFAIK this works exactly the same way for Bazookas, which I suppose are "soft weapons" instead - so tanks use their soft HP to defend against them ? ... which makes them better against bigger tanks ?)
increase the hard attack of both RPGs and AT guns to actually make them a decent counter to tanks.
I'm not certain how to do that without either increasing hard attacks of all infantry or also increasing hard attacks of all HVG tanks too ?
You seem to forget that, unlike Tanks, AT guns have the upside that their movement doesn't suffer due to their calibre, because they don't care about weight, so you can easily put a 300mm HVG on them. (Which subunit then will have the same logistic bulk as any other infantry : 5 decatons.)
You can't even *mount* a 300mm HVG on any tank besides a Monitor. (But then Tanks also don't get their firepower halved because of foot movement.)
I'm not certain how Bazooka calibre works, if it's just equal to firepower, then it starts at 100, and you need RPG for 200 and Guided RPG to get 300.
Or are they instead stuck at 100mm for the first 3 RPGs ("Hollow"), then you get 200mm for the 400 FP Heavy RPG ("Heavy Hollow") ?
(But then if AT guns are like towed Arty, you might also need Tech lvl 4 to be able to mount 240mm and lvl 5 for 300mm HVGs ?)
Were AT guns affected by the nerfing of non-towed towed arty movement too ?
I guess that there's still the issue that while HVGs have huge firepower/calibre (1200 for 300mm), as the OP said they have to face against Hard HP instead (which makes them relatively better against smaller tanks, especially with side skirts... but then smaller tanks cannot mount thicker armor !), and they are also much more expensive than RPGs ?
EDIT: Hmm, what about fighting other "hard defense" units than Tanks ? Especially (Heavy) Walkers and Automated MG / Turrets which can mount a *lot* of armor ?
