Not really, it is more to do with they don’t want to be the focus of all 6 enemies and if they die for the fight to be lost. That is a lot of added pressure that having 2 tanks currently alleviates.

Of course reactions are all over the place, so some tanks are throwing a hussy fit, but others (like me) are open to the idea. I still think it has a lot of negatives, but if 132 could solve queue time issues and not drastically change how most tanks work, I would accept it easily.
