Red Flags for DMs?

[Zanos]

I personally find it hard to believe that any player (except one who is a first time gamer and doesn't know any better) would stay in a game like the one he describes.

I recall him mentioning that he hemorrhages a lot of players, but it's fine because they were bad players anyway. Other options include not knowing any better, or simply being browbeat into accepting his views.

...and we're doing a "ToB is anime!" "Is not!" "Is too!" debate in 2017? Really?

It's [CURRENT YEAR] guys! There's probably a monk thread that's less than a week old if you want to complain about recurring discussions.
