Healers are needed in roulettes because the system won't match a random party without one. Healers are needed by default.
It being like this a long time doesn't really make it better, though from what I have gathered it has become worse over time and in the past War used to be less invulnerable.
The problem is not that you can clear content with all kinds of exotic team compositions. Sure, you can also do an all healer clear of casual dungeons but it'll take a lot longer. It's that 1T3DPS can apparently be more feasible or at least just as feasible as 1T1H2DPS, making healers effectively redundant in the trinity. You say it yourself, healers are necessary because the duty finder demands they are there. That is an external requirement. It doesn't necessarily reflect the true balance (or lack thereof) of the trinity. If that external constraint wasn't there then perhaps healers would be less needed.
