Lol how is his point lost? These stats are legit, unlike most of the claims you like to throw out on a whim. Less people playing a faction doesn't mean it's inherently more challenging. (although OKW playstyle does take a lot of practice to get used to) people might just not enjoy it as much. They sure aren't having a hard time winning in team games. Unfortunately nothing has changed about balance in 1v1 as well according to these stats.
I would argue the meta needs to settle a tiny bit before we can call it on what the FOTM new "OPness is" as everyone thought the PTRS buff would make Tank Hunter tactics unbeatable, but everyone quickly found out that was not the case.
USF saw a huuuuuuge change in meta, I think we need to let people adapt for a little bit. But I also think the reason why Ostheer sits at an advantage is because it got more Alpha buffs than the other factions did.
