Game development times are getting completely out of hand at this point. I really hoped that the advancement of game creation technology and more advanced engines, we would have seen sped up game development, but for the past decade we’ve seen nothing but the opposite go the point it’s just ridiculous now for some games.
This also poses the other question - who thought it was a good idea to show an ES6 teaser if the game was the better part of a decade out at the time of the teaser?
I found long ago that trying to balance my 5E encounters in any way, shape, or form is just a hopeless endeavor.
I just throw things at my party and kind of let 'er rip. Some end up hard, some end up easy, after a while you get a general gist for what they tend to be able to handle.
