nah OST and every other faction except UKF is good where it is. No need to change anything. Developers can't patch the games at the whims of fanboys crying for a faction. Some factions have strong mid games like US and sovs whereas axis have strong early start games. The late games are decided totally on unit management and skill levels.
Yep especially ost. They have all the tools through all phases to handle every possibilities.
Ukf need a pop decrease, need to reduce cp for Churchill heavies, need to return some resources with emplacement tear down, cromwell need to be cheaper
