The autofire range on everything should be decreased. The pack howie would be okay if the attack ground range was equal to its barrage range, like every other indirect. I haven't verified it by looking at the files but it seems to be 60 for autofire, compared to 80 for the Ost motor and something like 100 for the mortar pit, leig, and 120.
If the mortar pit's autofire range was set to ~50 (along with all the other indirect), people wouldn't complain about it so much. Most people are too lazy to manually target the mortar pit. They want a set-it-and-forget-it unit with 100 range. In game, it is sometimes hard not to go off on a UKF teammate when they are just letting the thing autofire at a moving squad (effectively doing nothing) while ignoring the mg that you need moved in order to take a point. Set it to 50 and they either learn to use it or just lose a lot.
AA: it's 65 for USF mortar. 80 for all normal mortars + Pack Howie. 100 for ISG/120mm. 105 vet1 ISG. 115 for mortar pit.
Barrage: 65 for USF mortar (80 on smoke on vet1). 80 for all normal mortars (which include mortar HT). 86 vet3 USF mortar. 100 for ISG/120mm. 105 vet1 ISG. 106 vet3 mortars. 115 for mortar pit. 133 vet3 120mm. 140 vet3 ISG. 160 Pack Howie. 212 vet3 Pack Howie.
-OMG that range on barrage on 120mm/ISG/Pack Howie!!11!
>>>120mm takes double the amount of xp to vet compared to normal mortars while also shooting at half the speed.
>>>ISG barrage is mostly not used unless you are countering UKF emplacements (AOE does not guarantee to use it in this way)
>>>Pack Howie only shoots 3 shells (which are great, specially at vet2) which makes it lackluster while waiting for the cooldown.
Opinion:
-USF mortar: do not spam it just like before. You are facing MG heavy strat or annoying garrison? Get one. USE THE FREAKING SMOKE, do not rely only on the HE barrage.
-USF Pack Howie: increase amount of shells and/or decrease cooldown on barrage. That's it. Oh, if min weapon crew could be set at 2, that would be great.
-OKW ISG: reduce AA range to 90, give it smoke, replace vet1 with Hollow shell mode (like changing munition with Sherman instead of it been a barrage), better AoE profile against garrison.
-UKF mortar pit: reduce aa range to 100. Give smoke at vet0. Replace garrison RoF buff bonus with "Light HE barrage" unlocked at vet1. Light HE shells are the originally beta concept. Lower damage (60), higher range (130). Reduced cooldowns on barrages.
