What did your Steadfast mechanic consist of?
It required that tanks pay less of an inherent penalty in their offensive output, but that everyone effectively pays a higher penalty (offensive and cumulatively defensive) for tanking, in that they get 'knocked around'. This doubled also as a way of allowing people to survive initial blows without making them sturdier in the long run, since their initially raised mitigation floor would be quickly knocked down. Think of it a bit like either granular vulnerability afflictions or normalized RNG (whereby initial dodge/parry/block chance starts much higher but is then reduced with proc success * effect of said proc). Steadfast simply reduced those penalties from damage taken, keeping you more consistent over further hits.

This would have faint anti-synergy with active mitigation, though only in the same way any two stacked mitigation effects (active or passive) have with each other when calculated at different layers (i.e. not calculated additively).
