My compete opinion on new monk is meh it's fine, yet another monk rework.
Honestly they should look into adding auras to characters to fix ui staring issues. When you switch stance have you glowing or something to show you should use your enhanced moves or something.
I don't think it's a major problem because as I get used to monk I can glance at my beast bar and memorize the next few combos. But yeah it could be handled better.
