in all fairness, I agree with the problem, but not entirely the solution. The supermen being described here relates to the Mary Sue phenomenon, which we all roll our eyes at and try our hardest to avoid, yet manifested via stats rather than narrative. But, this being a 'game', there are those who will find all of the shortcuts, exploits, and formulas to make their character the 'best' because it gives them the sense that they are 'winning'. Therefore, you end up with players abusing the system in ways unintended by the developers, because developers are purehearted and honest, and believe the rest of the world is too.
What the developers expect from us players is to create a character who has BOTH STRENGTHS AND WEAKNESSES, fears and desires, hopes and dreams, yada yada, and who will eventually fill a role in this fantasy realm society. At the same time, they don't wish to have programmatic classes and such, and want to give us players the autonomy and freedom to develop our characters the way we choose, and trust us to limit ourselves so that we don't develop into a society of ubermensch.
Another thing to keep in mind is, this is a game in development, and us current players are actually lab rats and testers. Some players out there actually enjoy exploring every single facet of the game, and push themselves to test the limits. Gods help them.
Anyways, you'll find that those players who are after the superman as their goal are basically rendered ineffectual when it comes to the core of this game and of this player community, and that is RP. I've been playing for a year now come one week, so I may be a newb in some eyes, but I've remained constantly active for the most part and in my experience, within roleplay, stats are basically ignored in favor of character reputation and the Rules of Storytelling.
Those that grind constantly (for that's what it takes to be superman) are, well, grinding constantly, and the most interaction you'll ever have with them is see them run past towards the dlayo pit fully armed in plate and dual wielding reinforced battle axes. Those that return night after night to suffer and rejoice in their character's losses and triumphs, to run the whole gamut of emotion and be left in catharsis, they may or may not care if your INT is 300.
