Thunderclap not having any potency is the best part about it. You can zip around like a madman and not worry about losing DPS.

That said, Monk does feel very slow in between Blitz windows and could probably stand to have something there. Problem is, since Blitz windows are (almost) always RoF windows any sort of oGCD attack would just be put into that, leaving the downtime still slow.

Frankly I'd like if the positionals had stayed, but PB let you ignore them. This way the Blitz window is completely unaffected, but in-between has a slight bit more engagement. Ah well.

As for Riddle of Wind, yeah it's an odd spell. It's essentially a 600 potency DoT that you need to stay in melee range of the boss for. If Monk had any synergy with autoattacks (more chakras, for example) it could have at least had that. Also a 90s cooldown is just so weird when one of their stated goals was to put DPS cooldowns on 60s or 120s timers.
