But a fighter can't multi-class to even the odds if it matters to them?No. But of course, I'm the only one who gets accused of making ridiculous interpretations of straightforward statements.
I said what I meant. Tedium is not simply in the eye of the beholder. It is also something that can be 100% intended for design purposes. And guess what? D&D used to use it all the time. It has been continually shedding that tedium over time, because tedium is simply not an enjoyable way to design games. Doesn't mean the existing Wizard isn't still tedious! It's just less tedious than it was in ye olden dayse.
Call it whatever you will. "Busywork," hoops to jump through, whatever. Some people have a very high tolerance for it. Others have a very low tolerance. I'd say overall I'm just below median on that front. But to have a tolerance for something, there must be a something for you to tolerate.
As I've already told you, I tried.
Ah, but of course you carve out the "unless that's what they specialized in," though "specialization" requires no more than picking a reasonable subclass (Bladesinger is best, but Abjurer and Diviner are fine too) and, as I've already told you, 2-3 effective spells (mainly shield, but other stuff is also good.) It really takes the Wizard almost nothing to be highly effective in combat, and ritual spells enormously extend their capacity.
Also, Fighter DPR is actually worse than other classes unless you stick religiously to the encounters per day stuff. Which was literally an entire other thread topic, very recently. Doubly a problem if you do what 5e actually tells you to do and was designed to do, namely, throwing large numbers of "weaker" enemies at the party, which was (allegedly) one of the key reasons for implementing "bounded accuracy."

The Solasta video game is D&D based and, if you play mods, it tracks DPR. I played quit a few mods for a while using a mix of PC classes. Most damage is done by fighters, next was the paladin, wizard is typically third or fourth. Many modules let you rest quite frequently. Admittedly it only goes to 13th level, but most people will never play to that level anyway.
In my own games which, heaven forbid, I actually use the expected budget for monsters in a single day and play the game as designed, the fighter also comes out on top or close enough.
