Saying this in the middle of an edition change, where feedback is being requested, is really pretty wild! We'll be able to say whether you're right or wrong when 6E/1D&D actually comes out. But what a time to claim that.
Everything that's wrong with 5E's Fighter is fixable, frankly. It's just not been done so far. I'll be very interested to see what 1D&D does.
Sure, but digital tools won't work for you, for example, and imho they and the general level of support are some of the main reason to run D&D. Even with the powerful building options in Beyond (which are hard work to use), you can't do what you're suggesting. But I'm not asking for anything as extreme as "charisma-based Fighter", I'm just suggesting the next edition of D&D needs to learn from 5E's mistakes (this is a post-mortem of the previous playtest after all), and particularly avoid the "apology edition" stuff which is clearly no longer needed.
This is such a fundamentally unfair claim that it goes past insulting/demeaning and into just amusing. The idea that because a DM doesn't make wild house rules and basically re-write the game in a way incompatible with existing material, they're "yelling at clouds" to voice concerns is just truly out there.
