That's an extreme take. If characters have comparable resources that are reasonably balanced, that's more than sufficient - for balance. But, whether some characters have daily abilities or all do, the 5MWD is still a mechanical issue.
Anything anyone says about their home game, yes. Analysis of the mechanics, no. The mechanics are right there, we can all see them, there's no dispute over what they are. So if there's a mechanical issue we can discuss it meaningfully.
And there's more than of us saying it is. So that's a wash. More importantly, the mechanics introduce the issue. Sure, both mechanics and whether you compensate for the flaws of those mechanics intentionally or unwittingly are both part of the issue. But one part is concrete and the other part is personal experience and unverifiable anecdote.
No, it's just a symptom. Being a bad design makes it a bad design. Kludging the bad design does not make it a good design.
Probably not, it most likely just going to be one of the penduluum deals, where they listen to whoever makes the most noise and over-compensate.
It is /caused/ my mechanics. Kludging the mechanics by distorting your game - or failing to notice their flaws because your play style happens to make an end run around them - is not a solution. Failing to implement a non-solution is not part of the problem.
The root problem is the mechanics. They could be a lot better, allowing for more styles of play instead of forcing one style.
And because you've had it for 30 of the last 34 years, and still have it in the SRD and Pathfinder, and yet are still demanding it be forced on the rest of us.
