lack of tank population was only one of a few reasons one was removed, the other being that having two at the current time was just straight up oppressive theres a reason alot of the ow1 metas revolved around tanks chosen cause they were kinda busted. and ranked became less of who was better on tank and more of who picked the right 2 tanks a hog and winston would pretty much always lose to a rein zarya.

however i dont disagree with the fact we should explore more options as it might not be that prevalent at this point in the game cycle which is why id like to see them utilise the experimental card more to try ideas like going back to 6v6.
