The Masterwork Armor Rules of 4e are totally confusing!
In some cases, there is no difference between a so-called Masterwork Armor and a normal magic armor with the same amount of enhancement boni. Or what's the difference between a Godplate and a +6 Fullplate? Both have AC+14 so this tells me that basically, masterwork armor rules don't exist because it's just a different name for a magical armor with a certain enhancement bonus.
But then I looked at Elderhide and saw this: Normal Hide+3, Elder Hide+5 (Minimum Enhancement Bonus +6)
According to this, if Elderhide has a min.enh.bonus of +6, the +5 has to be the base AC of the armor. A +6 Elderhide would then have AC11 (and in turn, +6 Godplate would have AC+20).
But then you get a problem with the prices because it says the price is already included in the enchantment!? So those masterwork armors are free (except for the enchantment, of course)??
Seriously, I don't get it. Can someone enlight me on this?
