I've always used Sheltron to mitigate tankbusters in Stormblood.

It helped regen MP to fix my rotation if I had to clemency someone.

It helped me regen MP to Holy Spirit when I was out of TP from AOEing.

It's always been useful from my perspective, but now has the additional role of being useful for multi-hit tankbusters. It'll act as a more effective version of Bulwark during big pulls.
