Worth leveling monk in Stormblood?

[Mahrze]

The thing is, I haven't really touched it since the ARR days. I know this new patch will bring some changes to it, but I'm really feeling pretty lost about Riddle of This and that.

The only riddle you'll ever really care for is Fire. Even with the changes in 4.2, the other two are still... gimmicky for a lack of a better word.

It just seems to me that monk has so many more requirements in order to do good DPS, like all the positionals and the chakras and the switching of forms.

You don't switch forms, you set to riddle of fire and that's it. Positionals also exist with DRG and SAM so you'll just be doing a little bit more with MNK.

And if you can recommend a good guide to help me catch up?

For it being worth it. It'll be up to you. But you already play DRG which is the limelight DPS along with NIN, MNK is just fun.
