Obviously what's good/fun for someone isn't the same for someone else and there's no right/wrong because it's all subjective. But having said that I just can't buy the argument that equates DM discretion with house rules, DMs are asked to make judgement calls by RAW. Stealth by in large falls into that category, for example in the PHB it says "The Dungeon Master decides when circumstances are approriate for hiding." So by RAW it's the DM just decides whether you can or can't try to hide. It's fair to not like that and prefer more clearly defined rules on when it's possible to hide, but the DM making a call isn't a house rule, it's the RAW text.Correct. (To be clear I don't agree with that, but in lack of a rule on Facing... any ruling a DM decides is a house-rule. I wish WotC had included on, or at least the option like in 2014...)
You can think I'm wrong, certainly, but I don't. RAW are not at the DM's discretion--they are, in fact, written. Choosing to use them or not, modify them, or make up there own is at the DM's discretion of course! And one DM might judge one way, while another might judge completely differently.
Yes, this has been mentioned in 2014, but sadly did not find its way into 2024 for the people who are new to the game and will be using these rules for several years to come.
Rules, whether house rules or clearly specified rules in the books, are more often then not there to provide consistency. Which is a good thing in many instances, but can also limit creative play which is a bad thing.
