Considering that the vast majority of this thread disagrees with you, queue times disagree with you, and the general community disagrees with you (Support & DPS being greater than tank) I’m going to continue disagreeing with you.
Right now Tank is the least impactful, least commanding role in OW, and the least playable.
All the available numbers and player consensus agree with that.
You’re an outlier.
You’re also chasing unicorn comps and scenarios.
The tank roster can be virtually unplayable with the wrong support comp. Same goes for the wrong DPS, but less so.
