The right solution is for WotC to dare present monsters and traps that deal damage and have effects that actually challenge level-appropriate characters.
The lack of actual challenge is endemic to 5th edition (once off the first few levels where the threat is real and the game works as you want it to)
Just to pick one bugbear: the One and Single Important Die Roll.
And the multitude of rerolls and bonus dice PCs routinely get.
Whether it's about wooing the princess, opening a magical prison or finding the hidden lever that opens the Tomb, the normal procedure is for the DM to ask the chosen character to make a roll.
Except that Bardic Inspiration, Dark One's Own Luck, Lucky, or any other such ability makes this single roll utterly trivial. (Beyond trivial if the Help rules are anything to go by, since you gain advantage on practically everything you do)
Adding a d10 to some roll is balanced on the assumption it's only one roll out of many. You made that save, great, here's another spell cast at'ya. You made that attack, good enough, but you make four a round, so no big deal.
But the excitement and uncertaintly of any social, exploratory or simply story roll is reduces to rubble. Or ashes. No, vaporized into atoms...
It's time WotC is made to answer for their savagely carebearian focus.
