This is elitist nonsense. Even ignoring the fact that CoH2 has a largely casual player-base compared to games like Starcraft 2, gaining feedback from all levels of play is vital for good game design. If Relic can make the game less frustrating and more enjoyable at all levels, that builds up a solid player-base. This in turn boosts sales, increasing funding and making continued, quality support for CoH2 in Relic's best interests.
tl;dr it doesn't take a top 200 to tell that things like plane crashes are universally negative game experiences.
balancing around top 50 =/= balancing only for top 50.
that is a design flaw, not balance flaw.
