Tanks are at their most fun when you can solo certain old Extremes and Savage Raids

I do agree Tanks should be masters of protection and mitigation - not of HEALING, too.

In the same way, healers should not be able to mitigate (ie. we should not have barrier healers, that's literally the job of tanks to protect the party). But we do. Tanks and healers have always been stepping on eachother's toes and that has only grown.
