Eh, opinions seem to go in circles around here. If you undo the clumping changes you'll go back to the days where 1 guy sticking out from cover got the whole squad suppressed. If you reduce the effectiveness of HE weapons against dense infantry formations we'll see more blobs. The reason HE was buffed in the first place was because of silly decisions to give abilities like rifle grenades and smoke to mainline infantry, thus giving them the ability to defeat MGs in frontal attacks.
Easily worth it. I'd rather my squads be unexpectedly suppressed instead of unexpectedly mush.
It might be possible to make the cover count as a squad modifier instead of an entity modifier (like when Osttruppen clearly are shown to have their accuracy bonus while most of them are in cover instead of all of them) in addition to fix up that other problem instead, but that'd probably also require reprogramming so the defensive bonuses only work when not flanked.
Most of the problems read here is that people think that 1 unit of yours should win against 2 of theirs...
I'm just saying, it's bullshit that my two Combat Engineers automatically lose to one King Tiger. 2 > 1, it's fucking kindergarden math, Relic.
