I am not picking anything. I am addressing the core of your argument. There is no need to go over every following sentence if that is wrong. You simply dont want to understand a very simple and obvious thing.
The facts are not supporting what you are thinking either and now youre going to "stop debating" and just loop back into repeating the same thing while you either dont understand what im saying to you or dont want to understand it - because it invalidates your argument.
And you can see that in the game itself. Make one of your character a hybrid build and make another a pure fighter and keep them like that.
See which one is better at fighting. There is no contest there at all.
Some smaller things can and should be adjusted still, - some relatively powerful spells are available very early and if that is adjusted the situation will look much better. But, there is no systemic fault as you presented it.
