I agree that they need new stuff, but disagree that Relic aren't open to fundamentally adding new stuff.
OKW were formally the worst faction in CoH2 from a design perspective... I mean they still are but they're now viable and palatable from a balance perspective due to the adding of the Panzer IV, the MG34, and the moving of schrecks to SPs. Before those three changes OKW were a shitstain, after that they're just a bit rubbish, but acceptable.
Relic were always more open to changing OKW, they were always taking it upon themselves to mess around with them like their attempts to make Kubel their starting unit. They've shown 0 desire to alter Brits in any way since release other than value changes, any time i've tried to open the dialogue with Relic and Mr Smith its just shot down.
I might make a video on Brits though as people seem to have these ideas of Brits being OP hammered into their head from how aids they were in previous patches.
