since it's lost a lot of its mitigation
Did we really ?

- we have good old stuff - rampart, vengeance, reprisal, equilibrium (now freed from tank openers)
- we have ToB now merged with now gone convalescence (so +hp and +heal) freed from minor dps boosting roles and memeheaval
- we have refurbed raw intuition - now on super short CD, flat 20% mitigation, with no cons (besides sharing CD with nascent)
- we gained nascent, god tier for trash pulls and somewhat useful for single targets
- we gained arm's length which doubles as quite good yet another mitigation for trash pulls

We (all tanks) lost anticipation (which statistically was not particularly amazing +30% chance for parry to happen) and awareness which had somewhat niche use in some scenarios (and was often paired with old version of raw intuition during trash pulls).

IMHO it doesn't feel like we lost anything relevant.
