D&D 5E The Minimum* to Keep 5E at a Low Power Level?

[GMforPowergamers]

I agree, CoS is doomed. It's hard enough to keep it from farce when the players buy into the horror. But is is really a democracy? Shouldn't the DM at least have a veto? They are the one doing all the work and hair tearing.

I have a gaming group that walks through deadly+ encounters like they are easy mod of a G rated video game... and I TPKed them in that adventure once... that is the 1 adventure that is tuned to be deadly.
