With Season 6 coming in a week already...

Monk does feel very weak, their build up for burst takes to long and it's easy to lose if an enemy runs away.

Their lack of range definitely stops them from being useful, even SAM has Enpi, MNK gets nothing but 1 30 second wind tackle that you can use twice.

Personally I feel like Wind Tackle and Riddle of Wind should grant a range increase to Monk combos so that they can hit on the run or have wind tackle convert into riddle of wind but rather than be another 500 potency tackle it's a 15 second buff that applies range to all mnk actions.

Dont think monk is weak they have the best burst tho it takes a while to build up you can basicly shut down someone alone if you use it correcly,
At least the good ones i have seen in feast.
