Again, since the comparison was between Arms and Ret, that's where the point of the discussion was for me.
Ret needs buff? Absolutely.
But to me claiming that Arms is Ret but better holds no merit, and in this I agree to disagree with Storm.
I know how Paladins were before. I played one extensively throughout BC and halfway through Wrath, stopping at around Ulduar to dedicate myself full time to my Warrior.
I have a complete lack of knowledge on how Ret played in MoP, but I know how it was in WoD and how immobile it feels now.
There's no need to list how it was before, because I know it. I know about Seal of Justice, Seal of the Crusader, deranking Seal of Command, how Judgement was out of the GCD, how important it was to have people full talent into Kings, to micromanage the procs of Art of War between Exorcism and FoL, all that jazz.
But aside on how the kit had more depht before, and it can be said for almost every class and spec now, Ret and the Paladin in general has utility that a Warrior simply doesn't.
