Healers have much less access to %mit of that kind, their gear has less Defence/MagicDefence stat on it, and so while you could do 1H3D runs, the 'normally a 20k autoattack' from the last boss in Yuyu-thingy new dungeon against a Tank with 200k max HP, becomes 35k per autoattack on a Healer who has 125kish max HP. This is enough to often interrupt your cast times, making healing harder (and making doing damage harder), the extra damage means you run out of 'free' healing tools like OGCDs or Lilies faster, and eventually you're down to using GCD heals that cost you damage. Even then, those cost MP, and you run an actual risk of running out by using them too much
