You would need to stop the design introduced in 4E that every class must be equally good at combat and go back to 2E where there were classes which were better in combat and other which were better at something else.
If 5E can even handle "something else", considering how gutted everything besides combat is.
5E does not have this. In terms of classes Rogues and Monks are behind the others in combat and if you choose the wrong subclass you are way behind.
Rogues and Monks are not as far behind fighters/warriers than they were in 1E/2E, but they are still behind.
I disagree completely about "something else" being gutted in 5E. With backgrounds, tool proficiencies and a variety of skills I find the mechanics in 5E to have the most "something else" of any edition, with Rogues as a class also being the best at this "something else" to make up for their below average combat abilities (Monks have no such save).
Some tables don't use those mechanics and on you tube and message boards combat dominates posts, but the designers did include it in the game, and they include it in their published adventures too. The WBW campaign can actually be completed without any combat at all ..... which must suck if you chose to play a blaster mage or a battlemaster.
