I'm good without ever having a tool of this kind but, I kind of would like to know if people are hitting mobs/healing etc.

Often I'll have groups where people are obviously not doing much. Like a dps puts the tank of follow for most of the dungeon etc....

While it might be clear that someone is just putting the tank on follow in a 4 person dungeon, it's a lot less obvious in something like CT.

I mean sure, you can carry people in CT, but sometimes it gets out of control.

Maybe they could add a Troll-o-meter that lets you know if people are contributing or not...lol
