Play games either not put out by WotC or games without those holes. Find a system that's as close to what you want as possible and house rule the rest.
All kinds of things. D&D 5E, D&D 4E, AD&D, B/X, WFRP2E, Labyrinth, Over the Edge 3rd Edition, Masks: A New Generation, Marvel Heroic, Cortex Prime, Cartel, EZD6, Traveller, Doctor Who RPG, Paranoia, Monty Python's CMRP, Call of Cthulhu 7E, FKR, The Extraordinary Adventures of Baron Munchausen, Dungeon Crawl Classics, Dread, Kobolds Ate My Baby, Risus, Lasers & Feelings, WEG Star Wars, Changeling 20th, Toon, Fabula Ultima, Blade Runner, Fate...and more. I've played in or run at least one session of all of those in the last 3 years.
Sure. That's one way to go. The other is to poke around and see what's out there and find a game that's close enough to what you want and house rule it the rest of the way to your ideal game.
