I am confused. What is the plan with the Infantry Sections? Last christmas patch they lost a RA cover buff but got compensated with better out of cover performance. Then the balance team decided to revert this and went back to the more static defensive style no one likes. Now you want to give them better accuracy on the move again? Seems very contradictory to me.
Main problems pre-summer patch: Bolster now available early due to added snares, Bolstered stock static DPS too high and too durable in the open; optimal for A-move blobs and beating Axis mainlines in pretty much all match ups.
Some target size was moved to the cover bonus because it was the only way we saw fit, to let Infantry Sections remain quite powerful mainlines in the early game that can hold their ground, while at the same time preventing them from steamrolling the map. It was never the primary goal to force static play, rather something of a necessary evil. To compensate for this somewhat, higher moving accuracy should make Infantry Sections a bit more mobile again. But without going back to the same problem as before, since lower static DPS (due to overkill) and lower out-of-cover target size should mean A-move blobs and stock 5 men performance in general will be much less powerful as it was pre-summer patch.
I don't fully agree with UKF's faction design either, specifically the cover mechanics for IS, and ideally I'd redesign things to get rid of it or at least turn it into something that's rewarding to use rather than punishing for not using, but a total redesign like that would have far reaching and unknown consequences which basically means it'd be a huge risk to take at this point in the game's life span (each patch can be the last one). So it's very likely going to be something we'll continue to be stuck with and we'll just have to work around it as best we can.
"Just completely redesign both basic Infantry Sections stats and Bolster" (and of course redesign half the faction to fill the anti-garrison, light and heavy indirect fire, elite infantry and AI vehicle holes while we're at it) is easier said than done, and would be a way too complicated and long process at this time.
Also regarding the underlined part. This pretty much proves my suspicion that the balance team is simply not applying the same criteria for all factions
I don't care about what belongs to which faction when it comes to balance, if something needs to be changed, I'll opt to change it. This was the case with Infantry Sections totally dominating Axis mainline infantry for a very low cost (only Bolster and A-move were needed, weapon upgrades and cover were irrelevant) ever since the faction ecosystem shift caused by adding snares. I'd have done the same thing if it was Volks/Grens/Cons/Penals/Riflemen causing major issues.
