I don't know if this has been confirmed or not (only level 54 myself) but some websites have this at the end of Blood of the Dragoon:
(Effects end upon reuse, or upon using a weaponskill other than Fang and Claw or Wheeling Thrust.)
So we might not need to keep BotD up the whole time. So an opening rotation might look like this?
HT-IR-ID-BFB-Dis-BotD-CT-PS-IDC4-Jump-Geirskogul-Ph-Sweep-TP-SSD-VP-LS-FT-DFD...etc
I'm not an expert and am not going to do the math to see if this will work OR if BFB will fall off before we get to FT. And if it would fall off before FT, would we rather have BFB for FT or for CT/IDC4? (I think BFB will fall off before we FT)
Where I put Jump-Geirskogul back to back, we need to figure out if we want 2+ Off-GCD skills in a row or if we want to let BotD fall off and continue weaving our Off-GCD into our rotation as before. Sorry if this is rambling.
