I was talking in general about base stance dancing cost becouse that talent actually with enough skill and depending on situation and encounters is very luckluster - you can get close to no use from it.
There is no clear winner talents. Everything comes to where you are with the content and gear. Clean example - picking extra defense and armor talent over 1h spec. At some point you gonna drop extra extra defense due to abundance on gear and pick 1h spec.
Same with going for unbridled wrath and extra overpower crit, shout specs, piercing howl being very usefull in raiding aswell. Warriors trees has abundance of decent talents for raiding and very limited points.
Bosses still dodge from behind. It depends highly on situation as you don't want to eat wingbuffet as OT... cleaves, breaths why not for most part.
