I’m for auditing the crap out of the talent trees. However, I don’t think adding new interactions is the first thing to do. I think that the class and spec trees need to be looked at and have talents shuffled.
Jade Walk can be deleted and Lighter than Air moved into its place. Fast Feet should be baselined and DoCJ could be ripped from all the spec trees and put in Fast Feet’s place which also gives BrM access to DoCJ. Statue should be deleted/baked into the individual specs, so Invoker’s Delight can be ripped from the spec trees and put in Statue’s place. Preferably un-nerfed. Improved Touch of Death can be baselined and SBT can be ripped from the spec trees and put in ToD’s old place.
Changes like these makes base monk significantly stronger, monk as a whole more of a pain to balance, and frees up points on the spec trees which makes each monk spec stronger.
