BRD Cooldown sequence?

[Bardo]

my way:

hs = 150 potency
wb = 45 potency
bl = 150 potency
vb = 35 potency
ss = 182 potency (((140 * 1.5) * 0.2) + 140)

You can't just look at 1 tick because dots "snapshot" the buffs you have up when you apply them. If you apply them and then apply straight shot later, the entire duration loses out on 10% crit chance. It does not update for each tick individually.
You ALWAYS want SS buff up before applying dots (and IR as well as much as humanly possible).

In order for your way to make any sense you need to do the math on:

HS->SS->WB->BL->VB
vs
SS->WB->BL->VB->HS

Delaying the dots by an extra global for a potential Straighter Shot proc vs not delaying dots. I think you'll find that getting dots up faster is a no brainer.
