If there is only one main metric it becomes the absolute one.

But more metrics also mean more room for interpretation.

And it will put the old metric into perspective and relativating it's importance.

Most top players here know it's a game but they play it nonetheless, at least in chest.

It's pretty hard to praise the "best" posters of the last year (or last n years) if they are hidden in a sea of antique posters.

Regarding patches, I see a way to improve selected best nodes.

User metrics, I don't know yet.

But anything which implies patches at multiple nodes without possiblity of testing offline and without godly privileges to role back is a PITA.

So we'll see if it's possible.
