It's really good. First of all, the eclipse buffs lasts for 45 seconds, so we finally can keep up while moving. Second of all, it's just a damage buff now, so we don't have a super ultra low crit cap. The rotation is a little more complex, though. It looks like you now always keep moonfire up, keep insect swarm up on solar eclipse, use starsurge on CD, and switch between wrath and starfire pretty often. When you're casting, you use up the buffs pretty quickly, so it's not spammy. I don't know how our dps is right now though, I don't have any addons on the PTR.
My only complaint is that your spells that benefit from eclipse light up when you have that eclipse. It's kind of annoying.
