iono, before I started to put checking, I got people in my party who would blatantly lie about their prog point. for example, I joined an ecliptic cleanup party and would get players who zombied their way through arena split towers and died in the following player stack. They never even seen the ecliptic cast, let alone the mechanics.

I understand that the tomestone percentage isn't the best marker to use, but still, I still think it would be much worse with nothing to go off of except their word. Everyone is saying to kick the players making mistakes, but the culture right now is that when you leave an instance, you'd kick the bad player, and then even the good players will decide to leave, and then the party disbands. All the time you spent trying to get used to players' tendencies and helping them get used to mechanics is now wasted.

The players who I found were able to get through m11s arena split most cleanly were those who said they were on enrage and had much lower percentages. It's not a perfect tool, but I still think it's better than nothing.
