DSR was just solo healed

DPS are entirely optional in dungeons. Hell, I'd wager TANKS are. It would be a pita, but you could probably heal + 3 DPS any 4 man in this game.

This is absolutely true, you can clear any dungeon with any set of four jobs you want, nothing is tuned in a way that would prevent it. It would be a LOT slower without a single DPS, though. And clearing content faster is objectively better than clearing it slower, especially when we're taking about content you're largely only doing to farm currency. There's no benefit to a purposefully slower run though, other than perhaps the novelty of amusing yourself once or twice by going in with 4 healers and getting the clear. So, while yes, DPS are also by no means mandatory on the lower end of the difficulty spectrum, they're still *desirable*, and one tank that can self heal through a bigger pull while the DPS burn things faster in turn is also desirable. Healers... not so much. This is what people *actually* mean when they say they're unneeded. Not that they're unusable or anything else couldn't be dropped as well, but simply that in general if you can get away with doing so it's always better to drop as many healers as possible... and that it is also very common to be able to do that with at least one of them in most content.
