Warrior %/s (KMS You & I + GMS Unleashed)

I don't understand what attack pattern lets a hero hit 6.36 times a second on a single target.
IS hits 3 times, with a 60% chance of AFA which hits once. So 3.6 hits on average.
With a Faster(2) weapon, IS time is 630 ms, so 1.59 IS on average per second, making for 5.7 hits per second.

Adding Panic whenever available only slows you down, since Panic only hits once and is a high-delay skill to boot.

Advanced Final Attack hits twice. It uses Panic so it does slow it down from 6.67/s
