Monks Broken Mechanic: Sweeping Wind Snapshot Overloading - YouTube
If you cannot understand german, this is the essence of the exploit:
1) You cast Sweeping wind wearing your hardest hitting items with as low attack speed as possible.
2) You then swap out to items with as high attack speed as possible.
The result is ridiculous Sweeping Wind DPS that uses DPS of Gear set #1 that is increased by Gear set #2's attack speed.
It is not unrealistic to see sweeping wind do THREE TIMES MORE DPS with this.
GG.
