I'm the tankbot of my FC and static. Even in Ramuh (we got our "legit" win there before this method), they make me tank it with Titan. So, in the end, you only get rid of ONE mechanic, which is the tank swapping and probably the stack building for that thunder attack. The rest of the fight still requires some coordination, because of the tether, the charm, the adds, the thunder stacks... so, no biggie.
