Sorry but now I must say you're getting intentionally inflammatory, Tony.Heh. 5e isn't really balanced around the 6-8 encounter/2-3 short rest day, that's just the point it gets closest. ;P Seriously, though, that guideline is perhaps the clearest example of Mike 'promising' us something in the playtest and coming through with it as promised. It's that "crystal clear guidance" he committed to. It's funny that so many people are so upset to see WotC deliver.
Why talk about this as if it's something entirely benign? What do you gain by phrasing the disrupture of people's games as something as wholly positive like the phrase "see WotC deliver".
It's not just "guidelines", Tony! It's a built-in balance-point. You can't just run the game like Blue any more if you want Warlocks and Wizards to be equals.
What is so hard about understanding that WotC no longer supports their chosen way of playing the game, and to respect that by not reframing their anguish into glossed-over sales-pitch language?
