The double application of HT just makes zero sense whatsoever, I'm not sure what you're going for there. It is "bursty" to get your oGCD abilities off while having your buffs up, but the accepted rotation already does that AND buffs your CT.

If a mob stays alive long enough for the IDC DOTs to tick all the way, your first priority with buffs is to buff an IDC, not to spam TTT. IDC > TTT is your most powerful two-combo set, therefore it's the best thing you can possibly buff. Focusing burst damage is neato, but at the end of the day, not the best use of your abilities.

I think you also mentioned using Feint, which is just not a good use of your time, as far as I know.
