Grenadiers can now use their own medikits as for flares, unless you go Churchill so the 25PDRs do more than scare the enemy off, Grenadiers can get sprint and camouflage from Commanders.
These things require commanders that will not help you much in 1v1s. You have to go full cheese or loose as Ostheer. Although this balance mod has done much, Ostheer will still be limited in options due to its lower squad sizes, weaker medium tank and underperforming Panther.
I agree that tommies have less utility, but claiming, like others do, that they are usesless without double brens is a pretty far throw from reality if you ask me.
