No, no you didn't. And even if the Berlin wall was constructed as you say, yes, there'd still be issues in the form of "no life basement grinders" and people playing cards that either you have one of the very few and far between answers in the entire game to, or you flat out lose to them (EG Gowen Rush vs. Guardian. Either you have a merc playset or a sala soldier/sin SS, or some other not-readily-available card, or you're done).
So you're right, in a way. I'll cut to the chase though:
I want to play a game in which everyone who plays the game plays the exact same game. When a player playing Soul Calibur 4 turns on Soul Calibur 4, whether he be someone turning on a playstation for the first time in his life or the world champion, they are playing the same exact game. The character the world champion chooses doesn't have some sort of line of computer pseudocode that says "if played by *world champion*, add 20 damage to each attack. If played by player who didn't unlock all the hidden widgets, remove 20 damage from each attack".
But that effectively is what Alteil is. Players don't play the same game. There is only so far that Kurina/combat monk/highland born hunter and samurai girl will take you. Certainly they're not going to cut the mustard against a deck devoted to buffing up a guardian, and then reviving it up to six more times with three oversouls and instant revives. Add in star dragon, and you get the idea.
If paying players simply wanted to assert that they were simply paying for more "content", and that they simply wanted to support a game they enjoyed--and not for an explicit advantage some way or another over non-paying or lesser-paying players, then there are many features they could pay a premium for which have absolutely no effect on the game, such as alternate art, avatar accessories, potions of various sorts, and so on. Heck, if the players were truly altruistic, Alteil could simply add a donate button and unlock the whole game to everyone. I know that in Chris Anderson's book (Free: The past and future of a radical price), he mentioned how one author simply posted his entire book in PDF for free, and added a donate button and said "pay whatever you think is merited out of the value of the entertainment/knowledge you got" (not exactly in those words, but you get the idea).
And it made far more than zero.
Nerf Elite Fencer. Change start skill to "target unit of agi 4 or higher gets AGI = 3. Then, this unit gets AGI = 4 for this turn and ATK +10"
For the great justice of the diverse meta.
