If the mode is not properly balanced (so a tank or healer becomes a burden), then the content sucks for tanks and healers, which might stop altogether (given that said content is tied to legendary, so mythic raid, progression) and become even more scarce. There should be something something to compensate the "loss" of one DPS slot, I don't know, maybe some pickable or consumable items that puts a DoT on yourself while increasing your damage, so that could benefit tanks or groups with a healer, while being impossible to manage for full DPS groups. But then the community would find a way around this shit to benefit it even with full DPS groups, making the content trivial.
But I get that's nearly impossible to balance such content around 36 specs, so Blizz decided to not do it at all and throw Tanks and Healers (and sub-specs - what if Ret Pals, WW Monks or Shadow Priests were barely viable ? Should they commit sudoku ?) out of the window. This content can be done in groups so just get carried noobz
