I certainly agree. It might be worthwile to restate the Paizo rule that; "Light weapons are two sizes smaller than the creature they're intended for, one-handed is one smaller, and two handed are equal." On top of that, as was brought up in the AMA thread, armor is of particular confusion, since there is no Paizo ruling. To summarize the suggestions from that discussion for you;
- All armors are equal to their creature's size
- They scale the same way as weapons, with light being two sizes smaller
- they scale similarly to weapons, with light being one smaller and the other two being equal
