You will note that the recipe in the OP does not state AA% for the hops. Your Warrior at 16% is crazy strong. You could probably go 1/2 oz to get it at the 80 IBUs spec'd.
Well it's all done with now. I brewed it last night. It was pretty hoppy but hard to tell what it will taste like once it gets a bit dryer after the fermentation. Wish me luck I guess.
What AA%s have other people been using?
