You can pretty much figure that 90% of those 1900 with maxed strength have the other stats maxed and the other 10% will likely too soon. bilbous' stats are all maxed but none of my alts' are anywhere close. Of course that 375k characters is misleading as I would assume at least 300k would be effectively abandoned.
This is of course speculation but...
Out of those 75k you basically predict being left we can't forget but to mention how many are just mules for carrying additional items... or alts that are rarely used and not trained (most players only train their main character but as mentioned before players can have like 14 alts or more).
The fact that 1900 out of much less than 75k active characters have maxed stats will probably still be worrisome. With the full 100 characters I see online (300 is the best I've seen and that was years ago) even if you said each of those 300 players had 15 alts you'd end up with around 4500 characters....
I know..Not all 1900 of those strength maxed characters are active, probably over 1000 of them no longer playing...But there are not 4500 active characters on Laanx either. Not even close. You're going to end up with a lot more of those maxed stats people then you should and thats the truth, and a lot more who are working their way toward maxing....I'm not seeing how this is going to hold true:
If you have STR of 200, you can feel good about RPing "strong" without us coding a super-complex system for additional precision. ;-)
But like I said, just my thoughts, not any facts.
