Just another fringe thought I figure I’d share:

What if instead of tankbusters being one large heavy hit you need to mitigate, which end up feeling like they don’t hit hard enough when very little mitigation trivializes the damage, if they instead inflicted infirmity for a longer period of time. So rather than the tankbuster itself being one hard hit that Varys greatly on how effectively it does this, the attack itself is never lethal, but is otherwise reducing the healing the tank receives over the next several mechanics. In that case, mitigation is more about making that easier to heal through?

Just something the came to mind from another Star Rail encounter.
