Do barbarian masteries still multiply damage?

[Pren]

Basically, I'm trying to determine if it's worth more than a couple of points in mastery now for a frenzier.

You've got double swing, which eventually goes to 0 cost, and taunt, which can be very useful at high levels, both of which increase frenzy damage by more than mastery increases damage. If they still multiply, then the added crit rate and multiplication makes mastery still worth maxing. If not, then I see mastery being reduced to a handful of point skill, like most other passives.

What's the scoop in 1.10?

Edit: Left out that taunt was also a consideration. I've always loved taunt, but it was pretty much a 1 point skill due to the investment. With a boost to frenzy, and possible serious damage reduction (from occhi's thread), it's also a big consideration.
