Five Seats Forty Specs
A Mythic+ group is five seats — one tank, one healer, three damage. 12 of 40 specs fill more of them than an even field would give, and 3 tank specs alone cover 72 in every 100 groups.

What is counted
Every Mythic+ group on the Blizzard leaderboards at keystone +18 or above, for period 1089, EU and US combined into one field. 13,053 groups. A spec counts once per group, however many of its players are in it.
Why the even share differs
A group seats one tank, one healer and three damage. Six tank specs share one seat, so an even field gives each 16.7%. Twenty-seven damage specs share three seats, so an even field gives each 11.1%. The gold line sits at that share.
What this cannot tell you
Presence is not strength — it is what people brought. There is no history here, so no trend. Nothing records which specs shared a group, so no composition is claimed. The damage shares stop just short of 300%, which is the trace of groups that ran one spec twice.
