I didn't say stock roster. They have too much indirect fire overlap in their entire roster. It's the same with all the Sherman variants. Relic should've come up with more diverse units (like the Jumbo). Swapping all kinds of things now isn't going to fix that.
2/3 of the sherman variants are only an issue becuase they provide nothing to the faction as the jackson is all you ever need for AT. they are victim to factiona design falling apart, not overlap. they DID fill roles that were not found elsewhere (AT unit that could take some hits) inversely if we walk backwards with that conclusin we can make other USF indirect units overlap less
mortar-
fast. cheap, mostly a smoke dispenser, can help dislodge units in cover/ garrison
pak howi-
mini mobile howitzer. get rid of the auto fire so its not a super mortar that can ALSO barrage at great range. focus on barrages. make cheaper.
now the mortar has a role even in tandem with the pak howi.
scott-
more or less what the pak howi is now but more mobile.
justified with the fuel cost it gives usf a constant bleeder alternative to rocket arty. maybe give the barrage suppression to act as a blob punisher?
now that the elefant/JT cant OHK the scott it should go down to a 2hk from standard AT so they dont get abused en mass as the range is enough combined with the escape smoke.
calliope-
quite diffeent than stock options, delivery system completely different and not an issue for overlap
priest-
heavy indirect barraging. not an overlap issue.
mortar halftack-
mobile with a variety of shells including the "fuck your medtruck" barrage
unique and not an issue.
now all usf indirect fire fills a niche and can coexist without one making the others pointless.
