This isn't to say that either position is either inherently better or worse. Personally, I think that there has been too much focus on the Druid mechanic and not enough on disintegrate; there seems to be a fair number of mechanics (and they are proliferating as the rules expand) that allow some type of recovery from 0hp.
I've always had issues with the Disintegrate spell in all editions of D&D. Even back when I was playing Baldursgate, I would cast Deathward on my party, to protect them against it... which of course did not work, because disintegrate is not a death spell. Then why does it sound like one? The word alone conjures up an image of someone being obliterated in an instant, which sure sounds like it would require a death save. There's just something very unintuitive about the spell, and I've never liked it.
