Maybe you'd think that it's irrelevant because it was "easy" content, but when we reached T5, T8 and T9 with my static, we went solo tank right from the start. We even tried T6 that way...not very successfully

Considering that tanks will soon receive several skills to mitigate damage on party members, maybe we could have a DPS "tanking" a big add for a little time while the five DPS burn it to the ground.

You're right that the Devs are trying their best to avoid that, but by doing so, they effectively corner their tanks into playing the same, making the imbalance obvious.

It's still irrelevant. There is still only one optimal way, and that could discourage players. It's like saying "It's not a big deal if there is only one BiS set, most people won't ever have it". If you want the BiS, you still have only one way to obtain it.

You're right, I didn't even try to clear A12S. Why ?
Because I don't like the actual tank meta. So, even if I put the effort in learning the fight to do it "optimally", it wouldn't be fun for me (In fact, it wasn't even fun to do A9S and A10S because I had to go WAR despite not particularly liking the job...).
If I knew there was a way to clear it as effectively with an usual setup, I might have tried it with my static.
