Just buff the other doctorines. M26 for instance is just an overpriced medium tank, Riflemen Company/E8 company is nothing about Riflemen, Priest cannot even hit a standing blob, Airborne lost its recon asset on the 260 ammo plane, Assault Engineers are worthless, etc.
I understand why I keep seeing the same doctorines over and over again, there's nothing else my opponents can choose from.
Well, Pershing may be a bit too expensive but it's good vs all targets and it's really fast.
The only thing which has bee changed for RC are flamers. Overall this doctrine is still good. E8 with good pen, RE with flamers and phosphorus.
Priest is really good agasin campy playstyle. It acts like it should. It won't wipe your entire army in second but can be devastating agasint blobs. I had plenty games with 3-4 priest killing Panthers, Jadgtigers
Assault Engis are everything but not worthless.
Well, P47 is shitt, I know.
