Too many DPS in m+: A different perspective

Depends entirely on the number set.
For example the Dark Pulse in third boss in CoT has a wide enough margin for error for all healers to be able to handle it without having to be a meta pick, but it remains a heal check.

The stated goals is to make it harder to hard-carry, and to put some responsibility on top of DPS.
It might be tuned so that if 1 DPS dies it can still be completed, but if 2 are dead it’s impossible. That would still be a bigger responsibility than what they have today, as all 3 can currently be dead for an entire boss encounter, but the boss will still be killed by the tank and healer (after a darn long time).

Edit:
Someone pointed out that this would conflict with the idea of maing hard-carries at recommended ilvl impossible, and they’re right. I withdraw from this and I think that if everyone is at recommended ilvl, a dead DPS should be mathematically impossible to hard-carry through a DPS check.
Ress that DPS or accept the inevitable wipe as a punishment for failing.
