Give everyone a "free post count" of, say... 3000? It would only apply to stats and class progression. Of course that's a lot, but the catch is that further points won't be gained until a true post count of 3000 is actually reached. It wouldn't hurt, even that is a drop in the bucket compared to everything that's ultimately planned (characters can still vary a ton when it comes to templates).
While a person with a higher post count will have the edge, someone with a "post count" of around 3000 would be highly capable of using tactics to their advantage... Something they would not have for a long time if they start at zero. This isn't a real game (yet), no need to introduce a "grind" for post count raising.

So... Discussion?
