Up to some point. In the worlds of CoH2 matchmaking, it means that there's a higher chance that MMR is skewed towards the faction with more players upon arming a match.
Note:
-Difference should be around 5 points, at most 10. What we have now is crap
-AT makes a lot of difference and i'll love seeing stats for it.
PD: i'm doing fine with the so called "Lostheer" with sniper play and skillplanes. Early on i'll rather have a teller than a LMG.
I've given up on trying to playing it seriously, have been pretty much only using inf doc etc. Spamming Osttruppen etc is certainly viable but frankly...nah.
