Thinking further about gladiator's resolve…
For me it’s a great talent and I will most probably be using it mostly as I really like the concept of it including its limitation to change stance in combat. But it is going to be a great pity if we will not be able to level through Warloads with it.
Considering the use we have of Battle Stance when we are in a prot spec build, I can see no reason why we should not simply bake in Gladiator Stance directly. Without Gladiator's Resolve, Battle Stance does not provide much more to a warrior. Even on the current game (MoP), if you are prot speced and you are questing, grinding, pvping or whatever, there is no point in staying in battle stance. You just sit on Def stance.
Also with the current talent configuration planned for WoD, as protetion we will totally miss out on Seigebreaker which I think is a great pity..
The way I see it, if you choose a protection build, battle stance should simply change to gladiator stance and offer what is currently planned for it in WoD, including the not able to change stance in combat. In that manner, we will be able to level in gladiator stance and we could open up a possibility to take seigebreaker.
It will then be a combat decision to either change to a more offensive or more defensive stance before stating up a fight
