I almost feel like if 1v1 duels were a thing, there would need to be even more rebalancing in terms of skills. Or something drastic, like a return of animation lock or something. Because XIV is the type of MMO where you just dump all your CDs on your enemy and pray he dies first.

XIV isn't an action game like TERA where you can dodge abilities and legitimately outplay people. I'm a PVP advocate, and I think XIV works fine in party PVP, but even I am skeptical that 1v1 would be worth anyone's trouble.
