I could, but this is such a basic component of dming that I feel like the designers really ought to include it. It's different in early editions, where there really is no math behind monster creation, but since 3e, there have very clearly been guidelines or rules that the designers use. Keeping those guidelines behind a veil is misguided at best.
In other words, I shouldn't have to create a thread to do what the designers should include in the rules, especially given that they were in the 2014 DMG.
I am still hoping that they will be in the new MM. If not, that's a massive misstep that shows such disdain for homebrew that I probably won't actually run the new version of the game. In fact, since 4e, there have been a ton of elements that make it harder to homebrew- over-reliance on digital tools that can't easily integrate homebrew material being one such element. Such elements are bad for the game, IMHO; homebrew is essential to allowing groups to play the game how they want to. Stripping all the optional rules from the new DMG is a decision that I don't much care for, but I hope it is a sign that we might get a book of options and changes similar to 3e's Unearthed Arcana.
