Most of those skills could remain whiled reworked too:

Battle Litany could be a Sks speed or auto attack speek increase
Brotherhood and Arcane Circle could just remove the damage buff portion, or have a side benefit like brotherhood doing an AoE heal around the monk each time it procs a chakra and Arcane Circle giving lifesteal/mana regen on hits for the party.
Searing Light be a wide range blind on trashs.
Trick Attack/Mug well... maybe could be so at the end of the effect it deals a burst of damage based on the number of total GCD of the party that hit the target, or empowers the next Assassinate/Dream Within a Dream. Kind of fit the idea of doing a sneaky attack while mugging the target in a group.

All random on the spot ideas but like, yeah, there is stuff to be done.
