Classic Best healer for M+ at the moment

Coming back after a break i see the meta has changed, i see a lot of holy pallys in the rankings. Is shamy still the King? Or has pally taken the crown for now? What about rdruids? They are not as present as they where in bfa, in fact you only see shamans and the more up you go the more pallys are coming. Whats your toughts about the current meta?(If you would need to chose one of the 3 mentioned classes what would probably the strongest choice?) via /r/wow https://ift.tt/3sGuNEh
