@Enil sorry i didnt really understand the maths, but yes, the second combo would mean. your demo would never have the DK & TWIN boosts, they would always fade just as your reached it.. and obviously you ud lose out on the xtra damage while reapplying DK & TWIN.
But isnt the xtra potency from getting an xtra 'empowered' bootshine and true strike worth it. as far as i know truestrike is our strongest burst attack, followed by bootshine (providing it crits).
im not sure how badly auto attacks would play a part in the above though.

@primezero
yeah, i know as a pc user you guys can actually side step, so you move from back to flank without looking away from the boss... but as far as i know, people on controller analogs cant do this.. without diamond targetting. but putting that on kind of traps you if your slow at switching it of for the mechanics.
