The only reason I'm making it seem harder than it is, is that I'm trying to consider all the things a Dev team would need to consider instead of ignoring huge chunks of the game. Devs cannot ignore numbers, balance is incredibly important.
The GCD and rage loss were a big part of them, as were the positive AND negative stats, and the utility limitations (Probably the most impactful thing about stances) was a way to balance the class as a whole. Thing is, If utility is limited in a way that forces you to lower your defensive capabilities to access it, Warrior tanks are basically dead in the water for M+/raids, because no other tank needs to do this. If defensive stance gives any defensive value, then leaving it removes said value, and creates a vulnerability no tank has to work around. So, can't limit utility, which removes the need to ever stance swap, which just makes them presences, which... you get my point, I hope. There's nothing wrong with liking them and wanting them back, we're all free to our opinions, but they were removed for a reason. They just don't wouldn't fit in the game, at least not how they actually use to be. They could make them passive buffs like paladin auras or something, but those aren't stances anymore.
Edit: Funny thing, I actually got myself mixed up on how GCDs and stances worked. Stance swapping doesn't trigger ability GCDs, but abilities trigger stance GCD, thus my confusion as it's been many many years. With that being the case, Stance dancing is literally just making macros just like people did in Vanilla. Much difficulty.
