Not having a tank means you have to be creative on handling the dungeon but is still doable with cooperation & planning. Not having a healer makes the run near impossible without it turning to an ultra slow, Clemency/Vercure spamming fest (and the run is basically stopped dead in its tracks if you don't have a RDM since tank self-heals are extremely limited outside of burst windows). You can say Tanks have more responsibility all you like, but they simply make the run more convenient, not necessary. Healers are far more important to the run than tanks are.

Also, Diversion/threat drops exist. It's quite easy to make a dps a de-facto tank by having one control enmity while the other doesn't.
well, from what i hear, healer/dps party its generally a problem of mana management. But a warrior/pld can actually go completely healerless sustainably.

I will say, if you said you have done it, then it can be done. However, i think that its probably more risky.
