The rules said Monks can’t be Chaotic.
The forums said, “Are you neurotic?
It’s poking big holes,
In 5E’s design goals.
Restrictions like that are despotic!”
Alignment restrictions are skunky.
My Chaotic Monk’s now a flunkie.
If Lawful must be,
Could someone tell me,
Which discipline teaches Drunk Monkey?
"Our idea of rules modules has a wide range of scope; sometimes, our rules modules might just be small tweaks and variant rules, while other times they could be large-scale changes and entirely new subsystems. We want people to make the game their own, and that means provided a whole array of possibilities based on what you, the players, tell us that you want." -D&DNext Q&A Blog, 8/29/12, Answer #3.
