Each "spammy" mitigation they do have even comes with a downside or limitation inherently: Sheltron uses Oath gauge, limiting you to 2 in a row at a time; Heart of Stone is the weakest as far as protection; The Blackest Night costs 3000 mp, which you only can pull of 3 ideally before bottoming out your MP (capped at 10000); and is a WAR uses Raw Intuition, it costs a usage of Nascent Flash and to use Nascent Flash costs a usage of Raw Intuition.
Tank cooldowns are actually more abundant due to the relatively low tank damage and the very spread out tank busters. You pretty much always have your 30% or 20% ready for each tankbuster and your short, fast recast mitigation like Raw. So you don't really "need" invulns for a fight, it often just frees up mitigation for fluff damage.
