For the fast conflags make sure you preload an HT and ID on Twintania (HT when the fireball for the conflag goes out, ID when the player is targeted with the Conflag).

Then you can: DE TT VT FT*, with oGCDs in between (you should have at least Leg Sweep available, if not Jump). You should also use the BFB when the conflag target goes out (e.g. you can see it's not you). BFB will cool down just as the second fast conflag goes out, or just after (as your first oGCD).

* FT TT VT FT might be better. I haven't really looked at it in detail. The DE approach will enhance Bard DD as well, so is probably more effective.
