Since when was it the Tanks job to explain fights?

I agree. It's not the tanks job. Anyone who knows the fight can explain it easily. Heck, the most commendations I got in one run was from a Steps run where I guided everyone through as my MCH. A leader isn't defined by what job he plays-- he's defined by how he acts, his willingness to take charge and to teach and guide people.

The only leadership I expect from tanks is them pulling mobs. They set the pace of the dungeon, yes, but that's about it.
