-Some- broken things? Like the Ranger class, Eldritch Knight having spell school issues, half the warlock being terrible (the other half is pretty awesome and you can just pick/choose awesome parts, so playable, but still), the sorcerer spell list, the elemental monk, the fact that gold has zero meaning in game, crafting rules are beyond a joke, spell list issues past level 10...
5e has a lot of issues. Just... not what the OP is suggesting. Like, if you complain that there's no lightning/thunder spells for a Tempest cleric from level 11 on, then yeah. That's an issue we can all agree on. Its very strange that there's little to no subclass support after level 10 in many cases, and you end up falling back onto the base class cliches. Granted, most games end at that point, so its not really seen, but still.
