Honestly, as a player, absolutely. I like no limitation on casting, especially at lower levels. And, I'm actually fine with Larian NOT implementing the limit as long as enemies aren't utilizing it like I described. THAT'S where the problem will come in. The last thing I want is for Larian to have some crazy high level wizard or cleric running up to your party to get at point blank range to the closest and then casting Spirit Shroud as a Bonus Action and then Fireball as an Action at 10 feet away from everyone in the party. 8d6 damage for Fireball plus 1d8 extra damage for Spirit Shroud plus nobody in your party can heal for one whole turn.
Yeah... that would be bullshit. So, we are kind of relying on Larian to be fair as DM and set up encounters that are beatable in some way, but that is true with or with out the 5e rule. Especially in the case of homebrew special NPCs it is on the DM to make them tough, but not total bullshit.
