ToolScore. Someone get on this!
Ok, I just saw this post at wow.com indicating that Blizzard is doing more to track when people vote to kick a random group member, get kicked, initiate a vote kick, abandon a group, or successfully complete a run using the LFG tool.
If we can have GearScore, I want someone to start working on ToolScore right now. I’ll leave the exact formula to you, but I’d add a fair amount of toolpoints for abandoning a group and excessive numbers of votes to kick, and would subtract points for sticking around for a complete run, especially in a run where someone has left or was kicked.
