actual tested haste data in the bottom of the flurry thread now:
[Melee Combat] How does Flurry Work?
weapon combos used:
2.6/2.6, 2.6/2.0, 2.6/1.4, 2.0/2.0, 2.0/1.4, and 1.4/1.4
see for yourself if same speed weapons make a big difference. It's post #69. Look at the line called "% extra attacks" for the relevant data for this discussion.
