You know, thank god for Garchomp existing, and the competative Pokemon scene as well, or else there could be no way you could compare this as a minor problem.
Remember that in the competative Pokemon scene, Garchomp had potential for sweeping entire teams, unless you have something that revenge killed it, and literally, a Pokemon's ONLY purpose would be to revenge kill Garchomp, otherwise it would be nearly useless on a team. But remember, you had to deal with Garchomp and 5 other Pokemon beside it that could beat what counters it. Garchomp was at a whopping 42% at the top of its usage, and alone it was like the buffed Meta Knight of Pokemon, beging fast, just as frail, and stronger. The Pokemon community is a VERY patient one, it took a year and a half or so of D/P to this very day, about 3 years since its release, they're still testing Chomp to see if hes not broken, and they still say no.
I'm not convinced MK is bannable until he even hits the usage of Garchomp. Remember, 1/39 at 36% is SIGNIFICANTLY less than 1/60-ish usable pokemon at 42%. Did I mention that Garchomp's #1 Revenge killer, Scarf Gengar, was at about 29% of terms of usage, just to get rid of it? Theres nothing even close to that against MK.
Yes, I realize you have 6 on a team as Pokemon, but remember, you also have stupid amounts of Meta Knight secondaries that should be secondarying a different character because of the better Mach-ups a different secondary could give....
I'd say this is a fair expression.
No bans until it gets rediculous. If you think MK's current usage is rediculous, then you've seen nothing. NOTHING.
