That's an incredibly bad marketing strategy.
It's not a marketing strategy. Relic doesn't put how they balance the game on the Steam Store page.
They balance the game for top level because
only the top and bottom of the ladder are really affected by it.
CoH 2's automatcher works on ELO: if you win your hidden ELO rating goes up, if you lose it goes down. You have a separate rating for each combination of faction and mode. The game tries to match you with an opponent with as close an ELO rating to you as possible.
For example, the automatcher doesn't know that UKF is a meme. If you play UKF you'll lose against opponents you'd have beaten as SOV or USF (assuming equal skill with all factions). As a consequence, your UKF ELO rating will be lower than your SOV and USF ELO ratings. Consequently, the automatcher will try to match you with
lesser skilled opponents than you'd have faced as SOV or USF.
For the majority of the ladder UKF works fine because players on UKF get placed into matches with opponents of equal ELO. That's why most of the ladder doesn't think they're a meme: they're being matched with players who can beat them
with UKF.
At the top of the ladder the player pool is too thin for the automatcher to do this. You can't give DevM a UKF opponent of equal ELO because there isn't one. In tournaments, there's no ELO safety net at all: each faction is judged on its own merits by top players trying to win and some are found wanting.
