NIN is overtuned and needs to get nerfed. RDM is in a similar level of OP due to how immense his damage is in relation to the utility. And no, they can keep their utility, but they need to give up some numbers to balance it out, objectively speaking.
Both TA and Embolden are superior in nearly every way to AoE balance due to being predictable. In content, an AST would be lucky to get two AoE balance in a ten minute fight, compared to Ninja's 11 TA and RDM's 6 Embolden.
