It's beyond me how many people are asking for Brit buffs. The sections are fine now, they've been buffed back from being overnerfed. I'm pretty sure the complainers want sections to be buffed back to their original stats which was downright broken.
Also, the "nerf" to the bofors was well deserved seeing that the Lefh is nerfed (yes i know, ml20 was nerfed too, but SU never uses them, cuz katy is so much better.) And the "nerf" was just to prevent entire squads (even sometimes retreating ones) from being annihilated by accidentally stepping into its firing radius for just 2-3 secs. Does the bofors still shred Ost LVs in 2 seconds? If it does, how can the UKF only players claim that Bofors actually received a meaningful nerf?
UKF suffers from systemic design problems as how OKW was before rework. The problem is that they don't have as many non doctrinal units which you could touch without making the faction play like "cancer".
There's small suggestions like allowing AEC and Bofor or making mortar pits more affordable but enable more counterplay and bleed (by making them have half their firepower gated by garrisoning units inside).
Regarding IS, the nerf was sensible but it didn't fix anything at all, just removing the faction from most competitive play. People still require bolster + double weapon to remain competitive.
I would give them some small buff (revert some nerfs) aimed towards early/mid but removing their late game scaling.
Ex: start by making bren better but more expensive. Make Bolster and infantry upgrades (medic/flare) occupy a weapon slot. Make the flare upgrade provide a single scoped Lee Enfield.
Objective is making IS more modular, without been a clear option having them as 5 man IS with double bren and medic/flare upgrade possible.
As healing is no longer a no brainer, you could make the forward assembly cheaper to 150mp and move that 50mp difference to all other upgrade (retreat point and doc engineers). It would be OH bunker + medic equivalent. I'm aware this could be strong, but i'm skeptic that a 50mp would now make it OP.
Alternative: only bolster occupies a weapon slot.
It was changed from a constant MP drain to an RNG MP drain. The problem is, someone needs to figure out how to make the Pak not be a slightly longer range mortar, while at the same time removing the ability to randomly 1-shot models.
It can't 1 shot outside of vet 2 heat barrage and it's not more RNG than a normal mortar. It's no longer closer to be as accurate as an ISG while having the AoE of the 120mm mortar.
