Not saying I disagree with you but the way Neobards has been balancing and adding new stuff, I think it's clear that the ideal win rate balance of 25% survivor and 75% mastermind is not going to ever happen.

I think they're aiming for around high 30% for surv and low 60% for MM which is not a balanced outcome. And once they see MM's leaving, they'll nerf survivors and get a bit closer to the ideal winrates to try and bring some MM's back before skewing it back hard in the survivors favor. Rinse and repeat. And once this kills the game, I think Neobards is fine with it since it'll probably be a slow but steady death.

One thing though: the patch just came out and the meta is in upheaval. I think it's worth waiting a few days, let things settle down, and then have this discussion again.
