Dragon Kick hasn't applied the debuff if you were not in the right stance.

My PB starter:

PB > Snap(GL1) > Snap(GL2) > Snap(GL3) > Twin S. > B4B > Demo [PB off] > IR > ToD > Fracture > DK (maybe BS) > True S. > Snap Punch > Howling Fist > DK > Twin S. > Demo [B4B off] [IR off]

I do this to get a 2nd demolish off with B4B boost. I've found if I use B4B before Demo and IR after, when Demo is about to fall off, I can recast with buffs still applied. I clip the last tick of damage on Demo, but having the buffs applied during the next demo makes up for that.

I notice you guys apply ToD first. Is it worth it to apply ToD at such a weak state (No GL/Buffs) rather than waiting 15-ish seconds (in my rotation) to apply it with GL3 and buffs? I could overwrite it once buffs are on, but 25 pot for 15 seconds (5 ticks) = 125 + 20 initial = 145 potency before I overwrite, costing the GCD to apply the skill, which could be used once I have GL3 on other skills?
