Guess I'll consider myself lucky. I've only recently hit 50 and started doing whatever 8 man content I felt comfortable with, and depending on the fight, party make up or whatever, I usually have a small conversation with the other tank about which approach we think best. I have no qualms going OT with a war present. I see nothing wrong with them tbh. I have complete faith in my ability, but my ego isn't so big that I just openly assume I have to MT.

I can see things changing as I start to get more and more gear, but I see no reason to step in as MT unless the other guy had never done the fight before and even then I'll work with them.
