Remember the one rule of D&D everybody forgets, no matter how much Gygax emphasized it: if you don't like a rule, don't use it in your campaign. In my game I allow any and all combinations of classes. I might even allow a Paladin/Assassin, but the player would have to come up with a really good in-world rationale for it.

FR. My Battle Smith Artificer can suddenly learn the Wizarding arts and summon a spell book mid-dungeon crawl despite most wizards spending their life learning those things. But despite being able to harness the weave into mundane objects, including armor, to enhance them, or create magic items wholecloth, and even create a living construct, I cannot actually create a magic suit of armor and become an armorer artificer, no matter how much I try.
Pathfinder 2.0 sidestepped this issue by having class-specific feats instead of subclasses. Just pick which features you want dude, no need to be silly about it. And you get a new choice of class specific feats often.
Mutants and Masterminds (and I think GURPS) sidesteps it entirely by having point buy with all the abilities and stats. You don't even have classes.
Sometimes restrictions breed creativity, though.
Or Savage Worlds where you literally build your "class" from the ground up
Or Pathfinder for Savage Worlds, which is Savage Worlds with Pathfinder classes converted into Edges (limited to one per rank).
Shit, I thought this is an anti-marxist meme then I read the community. It's good to see lemmy gaining popularity. :'D
