Honestly… For Troy you really can do like, whatever. I personally like the Clone as a bit of a distraction but you don’t really need him that much (and on the other hand, the barrier can help with all the projectiles he spams). In terms of augments… Well, assuming you are running SNTNL, there obviously not really a use for static field in this fight because he doesn’t have a shield (and neither do the minions he can summon iirc). As with most boss fights, a cryo heavy CCC build is probably not going to be optimal because you can’t freeze him completely.
Best bossing in general would probably just be Seein’ Dead with a bunch of happy little kill skills, and as with basically any Zane build, you’ll want Violent Momentum and Synchronicity.
But really, don’t worry about that fight too much, as long as your gear is up to snuff it’s pretty easy.
