Flurry giant relies on reasonably good gear (I consider hitting demos through sanc 'good' on that build) and one of the most annoying skills to spam, but it used to be way worse when 15 int was actually 15 int.

It also relies on actually being able to bash them and doing enough damage more than them for it to matter. I don't know if people stopped playing primarily high dex warriors and assassins, but it was often the case that you'd just be waiting for the 1/12 fights where you riposte enough (since you're not hitting them) to justify typing it. Add startup lag to flurry and that might be all that's left worth doing.

Anyway, as long as deathblow gets to exist, I don't care if a predictable 4 round, mv draining skill does great damage.
