I don't recall they ever stating that, though I'd love for someone to pull it out of the crevasses of this board and show it. And believe me, if it turns out that they intended this to be the case AND they failed to mention anything about it on their UO Gamecodes website (ie: if you buy this now, understand that in six months we're giving it away for free), there's going to be a ton of irate customers.
Really? I don't remember them just adding a sixth character slot into the game with UO:AoS, a seventh in with UO:SE, and an eight with UO:ML, and yet each expansion added new skills (with the addition of a race with ML). People are already getting the ability to turn a character into a gargoyle at will... why in the world would Mythic need to HAND OUT something that they charged everyone else for?
Really? So my purchases three months ago availed me of this TWO YEARS how? That's right, it didn't.
Frankly, I purchased it so I had additional storage, but unless they're going to bump me up to 60% after giving 20% free, I'm going to be very upset. Basically what you're saying is that those of us who purchased this "advantage" over you paved the way for you to get it for free -- because those of us who occasionally purchase stuff from the game codes store help to keep the game in the money between expansions.
If you somehow think you're ENTITLED to something you didn't pay for while those of us who DID pay for it get screwed over, frankly, you're wrong.
