Can anyone solve this P99 forum puzzle?

[mcoy]

This one is still out there:

I see all players of a particular class.
But they never return to me, alas!
It's not my fault it was never fully implemented;
I'm sure the devs have something intended.

At least I still offer some service;
it's nice to serve more than one purpose.
I'm pleased now, some might say I'm smitten.
Can anyone find something for my new kitten?
