I've only currently gotten Monk to level 70 and this is what ive been mainly playing.

Monk hasnt really changed much from heavensward,We lost a dot and got riddle of fire to replace our cross class dragons blood we used.Riddle of earth is extremly situational useage,Riddle of Wind might aswell not even exist to be be honest.Brotherhood is a great utility buff for dps.Keep in mind also that Mantra is now longer cross class skill so it's a bigger utility bonus than it used to be.
Monk dps can be great but we still suffer in some content where its not possible to keep up GL,This makes us overall weaker than other melee classes in those cases.
Monk can also struggle with positionals depending on the fights.We have true north now but the cd is so long it doesnt help much.

Ps Tornado kick is still completly useless.
