I feel that it will depend mostly on player skill. Recently I’ve received feedback saying “There’s nothing much to do for healing” from the healers so we’ve increased the attack intensity on Eden Promise Savage, and made sure the damage received is tuned as tight as it can be.
So they still ignoring the elephant in the room with their design philosophy, joy >_>.
All that says is for savage the last fight in the tier is as fine tuned as they believe for what they want.
Completely ignoring rest of content, completely ignoring that downtime will always be a thing and they have no plan to improve it at least to an extent to talk about it(which is the biggest complaint is that our downtime is incredibly boring), there only solution is to make the last savage hit slightly harder.
E12s p2 is nothing compared to phase 1 and phase 1 still has large amounts of nothing for healers to freely spam dps. The hardest part is Shiva icicles into Titan bombs after your past that, your healing isn't pushed until Lions and once lions are done, meh.
People don't want dps rotations but they don't want 1 button monotony when they start playing well on healers and nothing that has come out of Yoshi P's mouth about healers has indicated they are actually working on the downtime problems people have about healers.
More healing will equal less downtime but if the downtime is the same as now it will still be boring and monotonous. Make healers fun with stuff to do in their downtime so the reward for playing well is fun gameplay.
But it is just a brick wall at this point >_>
