Mike Mearls' posting on monster design last week made sense for the most part. Heck, the man was using AD&D 2e as source material. Kinda hard to find fault in someone that does that.
The Grumpy Dwarf doesn't tear apart 5e posts for the sake of tearing apart 5e posts (although some may feel otherwise), he does so because something(s) in the post piss him off. Nothing last week really pissed him off, and the Rule of Three was boring as hell - so no Grumpy.
This week's Mike Mearls' Monster Mucking might get Grumpy to write something - we'll have to take a closer look at it. It won't be happening tonight, as I'll be running a DCC game and Grumpy Won't have access to to the computer ;)
