A possibly radical idea. What would the game be like if all "stances" were non-existent?

Currently, we see the following almost on a daily basis:

"Oh sorry, I forgot to turn on Defiance / Deliverance / Shield Oath / Sword Oath / Diurnal / Nocturnal / Cleric / Fists of Fire / yada yada yada...."

If these stance modes were removed and were all simultaneously "active" in the background so to speak, would that make playing the associated roles more fun?

Pros and Cons?
