That said, it would be silly to use blindside with vorpal thrust since the combo bonus is increased crit rate. It's better to use blindside on something that a.) doesn't have a naturally high crit rating, b.) is a single hit WS, since blindside only effects the first hit of a multi-hit WS and c.) is at the end of a combo so the direction doesn't matter. By process of elimination, that leaves you with doomspike.
Thanks Zetsume. I guess that makes sense.
