Yes, there are artifact traits and such it won't benefit from, but you're not going to have those while leveling to 110.
It's also going to depend on both mob tuning and your gear level relative to it. For example: Chaos Bolt opener that triggers Eradication, Immo, Conflag, Demonfire, Shadowburn. That's a SS neutral sequence using two short cooldowns, so you can repeat it pretty often. Is that massive overkill? Then you'll probably want to go Soul Conduit and shorten it to Chaos Bolt, Conflag, Shadowburn. Is even that overkill? Then maybe you want to keep Demonfire so you can alternate between using Chaos Bolt and killing something just Immo, Demonfire, Shadowburn.
Oh, and here's another stray thought. I don't recall seeing anyone post about testing for the interactions between Demonfire and the new GoSac. If GoSac can only trigger once per spell, it's nothing special. But if each of Demonfire's 15 bolts has an individual proc chance, and you can get multiple GoSac procs off a single channel? That's a synergy worth writing home about.
