Yes, I'm also not a fan of making honor mode so that it locks people out of content. Limiting long rests severely will just make some classes weaker and others stronger -- which is useless when you can beat the game with 4 characters that barely need long rests to start with. The same goes for taking out multiclassing. The gains aren't worth the losses.
If shop inventory of merchants doesn't reset, initiative is reworked and optimally much harder to win, enemies have additional resistances, spells and immunities I would already be pleasantly surprised. Anymore shouldn't be a default setting, but optional.
