Just thought I'd point out to you guys so you can actually argue about Formless correctly.

It's not magical damage. It's non-physical damage. There is a difference. Formless is a great ability, not because it's overpowered, but because it gives monks more versatility.

As others have already said here, it's not the ability that makes monk too strong. It's the content.

Complaining about Formless in Delve is like complaining about Mighty Strikes in a zone where your 2 hour abilities were constantly reset.
