He clearly didn't and I never stated such thing. Though Conan was a fighter, and I was using D&D as an example how they differenciate both types of fighter (the heavy armored one vs the one that wears none at all). One was a bag of HP, a reckless fighter and the other one a impenetrable one. As a side note, you can create a tank in games like Pathfinder, they are just not played the same way you would play a tank in an MMO. There are limitations. Have you read the feat "Antagonize" or read the class "Luring Cavalier"? (I personally consider Pathfinder a far superior game than 3.0~4th edition). They pretty much aim to catch the most of the monsters' attention.
People are constantly swinging between opposite extremes: pure reality rules (involving physics and whatnot) and going full fantasy where everything is possible. A credible fantasy setting mixes both. Yeah, in XIV you have a dragon that, if we follow the rules of our world, they would crush you by stepping on you. True. Yes, in the real world an arrow can penetrate certain parts of your armor and kill you. Yes, in a pure 100% fantasy world, you could defeat the God of Darkness with a piece of stale bread because "it's magical". But there are rules that must be followed to make it consistent and not just a box of chaos.
Let's say we're playing in a high fantasy world, and you're wearing an armor. For all intended purposes it SHOULD protect you, because you're wearing actual protection. It looks credible, because you're fully covered. No matter how big the enemy is, no matter how powerful they are. But we're in a fantasy world, it means that the armor itself should grant a higher defensive rate, way higher than the real world's counterpart, that's why it works. I think XIV follows that rule, that's why almost 99% of the sets you'll see here, would cover your body. They look heavy, they look sturdy. Now when you see a bikini set (excluding glamouring, that already has been explained several times), it makes you raise your eyebrow. That's why there are several sites that mock these types of designs. It doesn't look credible, even if we're in a fantasy setting (otherwise debates like this wouldn't exist).
I have already stated what my feelings about that particular sets are.
