The main issue with the Scott is while it's very good at auto-fire, probably too good, it fails to serve as functional artillery for the late-game of USF. It's AOE profile is very good at killing models, but is very poor at wounding or damaging models which is more prominent on the barrage which is known for very poor accuracy and you need to deal good AOE damage since most shells from barrage abilities don't land directly on target or are fired from further ranges into the FOW.
It's not serving the USF faction well enough in its other function as artillery to compensate for the lack of rocket or heavy artillery, with its best performance being Sherman HE lite.
That makes sense. Although, from what I played the Scott in the preview, it seems to be overnerfed. Furthermore, how does that synergize with the nerf of pak howi? Why would somebody go for pak howi outside of static emplacements barrages? It's slow as it is so moving targets are a no-no. Both in autofire and barrage. So now you have a scott with the accurate, albeit lower damage barrage but useless autofire in 3v3+ and pak howi that is great vs encampments but also pretty useless vs anything that can move. Not to mention the existance of stukas and werfers (+ lefhs).
Of course that is from the perspective of 3v3+. Maybe in 1v1 with much less units on the fields and unit combinations, these changes work. Don't know if your team's changes will translate well into the team games. Especially the Panther that got a pretty hefty accuracy bonus on top of it's already great stats.
I frequently field pak howits in pairs in 3v3s and while truly great at both damaging and killing models, experienced players that I played against back when I was rank 13, easily denied any sort of pak play with counter barrage or stukas.
Same as how ostruppen deserve a nerf in 1v1 modes but not in 3v3+. Or how 5 men grens are OP in 1v1 and not in 3v3, etc.
Best example would be the M20 buff. While it's useless in 1v1s, it's pretty pretty good in 3v3. Good utility for late game. That 20 seconds quasi buff won't convince anyone to go for it in 1v1 but won't make no difference in 3v3s.
I trust you know what you are doing and would only ask that you do not balance the game around 1v1 only.
