Ah, so about that.

True North is still on a 45 second recast as per the tour notes. Dreadwinder, which initiates your twinblade combo of positional (flank/rear) - mandatory doubleweave - opposite positional - mandatory reverse doubleweave, is on a 40 second recast. You'll also be using this combo specifically to realign your buffs just before Double Reawaken to keep them from falling off. So no, on average you will not be using True North to bypass this. They learnt their lesson from Gluttony.

It creates an interesting question around keybinds though, because you ideally want four connected buttons on the same row that you can glissando in both directions while being able to pivot on your strafe keys. I almost wish I used a split keyboard setup instead of keyboard and mouse.
