Why doesn't every templar just go around spamming this whenever they need to kill someone?
The animation is so quick that you can get to the last hit of the next spammed jabs for the stagger before the enemy has a chance to recover/get out of the way from the last stagger.
If your enemy ran out of stamina and/or you have some good aim, this is basically a surefire kill. Anyone wanna tell me why I don't see this happening all the time? Or even explain to me why this isn't such a good ability to spam in pvp as I think?
