this is for the top 2000 keys. Its not like the data is from all keys, so your pally representation in low keys would be moot. You’re getting top-end classes from the most efficient tactics available (META).
META representation would be a % of top runs, not the top class overall. That would make this a dumb metric as you would have very little variance in anything.
By your logic:
arcane - 15%
balance 14 %
ret 15% ( yes, they’re meta )
Based on your criteria; These three classes are meta. every other class is F tier, disregarding 65% of 2000 runs.
Yep, this is how meta works. You would be one of the top classes in the top % of cutting edge keys. It means that you are completing the top keys possible. This way you could have multiple high-performing comps. Currently there is a high level physical comp and a magic-based comp.
