First, I wouldn't drop Intensity. I really, really miss it. It makes me absolutely unable to AE at all, and I hate that. It is so bad I actually want to take a mage along in instances where AE is required...
Also, shardtracker has spelltimers, so timing Conflagrate is very easy with that. I recommend everyone to install it, so you can also precisely time when you need to renew your other DoTs. Also, it's really useful for banish etc.
Next, Corruption is nice against rogues yes. But on the other hand, if you're really into the whole seduce thing you'll probably only use Immolate anyway, so you can remove the DoTs and reseduce whenever you want. Corruption doesn't really fit into this all. Besides, IMO corruption only really comes into it's own if you also have Nightfall. So all in all, I guess a Conflagrate build is better complemented by Demonology.
Finally, yes the ZG robe seems quite uber. Although being revered as a requirement is kind of a no-no to me. I guess I'll first go for the bracers, +sta & +dmg FTW.
