Basically, because in a year or 2, the top 10 folks here will be able to with 1 shot jack up someones rep 10 stars, while the bottom 10 folks will -never- gain any, unless one of the "gawds" reps em. Completely defeats the purpose of the system. I don't even use it anymore because I hit so hard.
It's a system thats supposed to be fun, yet hold some meaning towards poster-quality, yet in checking where rep points are being issued, it's really turned into "I disagree with you in he study so heres some neg points" and "yay you post a lot in chat, heres more points, yay another star, go stud go."
The other thing is, an occational reset of the system is good, and recommended. It rebalances the field, and in truth, the cream will continue to rise back to the top.
The changes were announced some time back, but I got sidetracked with life and haven't had time to prep for it until now. So, this is a couple week heads up.
I'll be posting the revised scoreing system shortly so we can tweak it before it goes in. There's also some enhancements that should theoretically keep things better balanced for a long time to come.
