Given that we are expected to go into HW sync'd content some are Alexander raids, 24 mans and extreme primals, Blu was sorely needing a cheaper aoe heal, a potent single target heal, esuna(Doomgaze etc) and a raise to fulfil the healer role, i would say this is welcome.
It also needs a way to dump and generate aggro and a cheaper less potent cd for tank role.
Also needs a significant Dps boost due to enrages in some of these fights are tighter than ARR content.
