Keep scrolling down. Not that there needs to be "compensation", the faction is arguably overperforming.
I did, all I saw was a slight speed buff to the churchill and a slight buff to the 17 pounder. This is ignoring all of the issues with Brits base faction. Such as AEC being overpriced, no vehicle snare, no proper handheld AT weapons, no building clearing tools.
Since you are touching brace you are hurting the mortar pit, which would make their indirect fire even weaker(Their building "clearing" tool).
The faction isn't over performing, especially since they are rarely played seriously. This sounds like a sim city commander problem.
