I now think one unit that could really use a buff is the Katy. Not a weapon buff, but actually a mobility buff - so that it can respond quickly where it's needed most against strong, vetted OKW. And also so that it can escape from panthers - because it gets 1 shotted most of the time.
Needs to be able to get into position, fire a barrage and get out again fast. Maybe a health buff so it can last long enough.
RUS needs help in its T4 anti-infantry line-up. Maxims keep OKW at bay now, but kill a lot less. That has to be catered for elsewhere.
