Not current one, but yes, had my fair share of it in Legion/BfA and SL. Started as OT and picked up MT at the end of BfA. This is not some gotcha - outside of progression when you are actually getting blasted, tanking feels like being a 4th healer in a fight which only needs 3.5 healers. Not even talking HC/Normal tanking which is what most people who raid non-lfr will be doing, I have no clue how they manage to stay awake.
