I'm OK with them being different skills, even though there's not really any possible scenario where you wouldn't want either of them up, it's one of those things that makes PLD and WAR subtly different to each other.

What I'm not OK with is PLD getting their stances the wrong way round - WAR gets their tank stance at 30, Sword and Shield Oath really need to be switched round to make for an equal levelling experience between the two. You could argue that not having ShO for another 10 levels forces you to get good at managing aggro when you don't have all the tools to do so, but in practice it's just annoying and makes you a sub-par tank for a big chunk of the game.

Also, for the love of god please take them off the GCD and stop them breaking combos.
