If only someone made a mod for that
Lol. I still to this day wish that was a part of the live game. It’d fix so many problems pertaining to indirect fire and countering it as brits.
As for OP, I think a lot of points you make are pretty good, as for a lot of the other suggestions of users in this thread.
My 2 cents:
IMO infantry sections should be tweaked and the cover changes rolled back so that they’re good in cover but fairly bad out of it (much like ostruppen). I think their veterancy bonuses are kind of shitty too but I don’t remember for sure. Could somebody who knows their way around the game files post those? Also, I think brens should receive some sort of cover based bonus on sections too.
I think the comet definitely needs it’s main gun bugged against infantry but I think it’s penetration is fine as is and it already has so many abilities that giving it HVAP or DS rounds might be a bit much.
Churchill smoke is a bit silly and should be removed (and replaced with smoke shells like you said) IMO, but other than that it’s more or less fine. JP IVs counter it pretty well IIRC, and stugs and panthers do okay against it too.
I like ShadowLink’s proposal for the Cromwell as well.
I think snares will help the firefly perform a lot better and cover for its general sluggishness so IMO it’s fine as is.
The AEC is a little slow in general especially compared to the puma, and the treadshot could use a bit more responsiveness on the first shot and should be viewable on the move IMO like it was before, but other than that I think it’s more or less fine. The smoke seems a bit finicky at times too (much more so than any other analogues).
The base howitzer mechanics could use some love too. Even just a free smoke barrage callable by the sniper and pyrotechnics sections would go a long way, but I think a slight throw range increase (especially on the sniper) would help too.
