Best Claws secondary and archetype?

Sometimes it feels like I've eaten a discarded cake labelled "Smash!" and been transported to a hallucinogenic world where only I can see that scrappers do more damage than brutes. In the case of claws, it appears fairly egregious. Brute claws seems like it might do more single target damage in high recharge scenarios. For it to remotely compete with spin on a nine second timer, you're going to have to be at the recharge cap. Or use eviscerate as filler, I guess, but I'd rather "focus," hehe, on doing double stacked followup spins.

I admit I've literally never made a single spreadsheet about this game. If nothing else though, you're applying that many more oblit or armageddon and reactive procs, which surely must count for something.

So, I've been thinking of making a claws character.

So, Scrapper or Brute (I already have one of each so that doesen't matter..) and what for secondary? (/Fire /Elec or /Dark?)
