Also, I thought I might add that the chart there is somewhat outdated. There is an attack speed reduction of 80% that applies to all sources of attack speed modification. But, back in the days before this existed, a lone DRK/SAM with the best Haste gear available, Soul Voice'd Marches, Haste, capped Desperate Blows, Hasso, Souleater & Blood Weapon up could pretty much destructinate anything in the game within seconds because they were literally attacking 16 times faster than normal and hitting for more than 12% of their HP per swing.
