Oh, and the DPS sure can't clear the heart phase either if they are in AF gear.
Well obviously full AF and low accessories isn't enough, but an average ilevel of 60ish was/is fine to do all HM primals as a DPS or Healer, providing you have HP and a decent weapon. I can't vouch for tanking gear personally, but I have managed to heal tanks with a mix of AF, 60 dungeon gear, and DL.

Not to mention you are also including Ifrit and Garuda in your rule, where at least one of them is doable in full AF.
