The answer there is to just stop worrying about micro-balance or even mid-range balance and just accept that some characters are going to be significantly better than others in some situations and-or against some types of challenge. Then it's on the DM to mix up the challenges.Ideally yeah, but the game has trouble even balancing ONE temporal unit of challenge, so I find it hard to believe they would be able to pull off multiple units in a single game. There's not standard length for an Adventure, or a Campaign for exemple, so how do you balance out the mechanics so that player have the ressources to overcome the challenge? Let alone balance it so one character doesn't obviate the participation of others? At best you'd need a type of reset mechanic (AKA rest types) for each different unit of challenge AND each classes would need a suite of ressources that fit each unit of challenge (AKA an AEDU style system) with maybe the ratio between each tweaked to avoid samey-ness.
If the characters find they haven't got the resources to overcome a challenge then it's on them to figure out how (or if) to proceed. Not every challenge is defeatable.
