Bloodsown Circle should fall off as soon as you hit 8 stacks

[Rongway]

You can't use plentiful Harvest until bloodsown drops off. sometimes causing you to miss a gcd or two and ruining your opener. Particularly the early enshroud combo

Sometimes? If it has a fixed duration that prevents you from performing the actions in your opener when you intend to perform them, why are you planning an opener that wants to use those actions during that fixed duration? Why aren't you planning your rotation around not being able to use Harvest during those 6s, since it lasts 6s every time?
