Guards Rifle wonder the battlefield like Terminators, massacring all they encounter. Unlike Shock Troops, which are vulnerable to any armor (that's the balance), Guards are great against both armor and infantry. In my experience, in both using and facing Guards Rifle, no German infantry stands up to them, not even non-upgraded PGrens (which do better than Grens but still fall short) and German armor isn't a worry obviously unless it's more than one vehicle and even then, I'm likely to do a good amount of damage before forced into retreat (and that's assuming i'm unsupported).
As doctrinal call-in's Guards should be potent, and they certainly are potent as it stands, but they feel too good.
Shock troop reinforcement cost was increased and that helped, should a similar adjustment be done to guards? Are they fine as-is, why?
Your complaints about balance before were somewhat justified. But now with this new "guards are op" thread, with nobody ever making this claim before, id say you definitely lost your credibility. Id change the title or language if I were you. And maybe hold off on making a new thread for a while and try some strats to beat sovs.
