Sco of Method ranks the tanks in a recent video. He ranked them BM > DK & Bear > Pally > DH & Warrior, but his chart showed them all very close, and his closing point was...
"This is the first time since Legion release that I think the tank balance is really good from Blizzard and that going into Progress raiding, you could play any of the tanks, and they would be viable even at the highest level of raiding."
What do you think? Is this the best they've done so far? Or maybe we have to wait and see? How will preconceived notions and confirmation bias affect the outcomes? After all, there are a lot of geared bears out there already.
