Personally, I'd rather you scrap the Armoury System then Lock 1 Job to 1 Weapon.

Have you actually fought things in WoW? I mean beyond just Deadmines or Ragefire Chasm. That's a pretty bold claim, and one that would also get you laughed out of any raiding guild.
Again, why does it have to be this way? Why must the choices of individual players get tossed out the window? A job system is not an excuse for such a thing to happen. Was not in XI and is not here.

But it happened. And it will happen again. Because of the distribution of personality types drawn to MMOs.
