D&D is making changesWhat this data tells me, albeit with a small sample. Is that a significant number of people can enjoy playing Fighters (unless all these people are being tricked or forced to play it until level 7 at gunpoint of course). Significant enough that D&D are not going to make the kind of changes that a small but very vocal group are making. The data showing the popularity of the fighter and now that a purely non-magical fighter is pretty conclusive to my mind.
Every caster after XGTE is magical: Echo Psi Rune Knights
After XTGE almost every martial feat is magical.
And in 5e 2024,almost ever class is magical, feats are core, multiclassing is assumed.
And WOTC will make more books.
The nonmagical full class fighter past level 8 has been given up on.
