910 boomkin here, and I enjoy the lack of RNG in the spec pretty much for the reasons that Preach outlined. I'm able to have a plan going into each and every fight, and I don't have to worry about making modifications to that plan on the fly to take advantage of RNG aspects of my DPS rotation. Because there are none (barring Oneth's, but that's pretty minor).
Not super thrilled about the spec overall though. It feels weak, and the upcoming changes in 7.2.5 aren't doing much to fix it. They're nerfing our AoE, which it tough because it's difficult to achieve a balance (AYYYYYY) here: Starfall is amazing on fights with long periods of cleave, but sucks for burst. The removal of haste from Starfall exacerbated this issue.
And adding damage to Starsurge is just reintroducing the issue they had at Legion launch. Too much of our damage was tied up in Starsurge. In 7.1, they moved some of it out of Surge into Wrath and Lunar Strike, and now we're going right back to buffing Starsurge
