I have heard from someone in one of my daily heroics that there is a way to quickly mark targets with Skull, X, Diamond, and Moon. Would it be done in key bindings make the shift+f1, shift+f2, and shift+f3? Or do I have to down load a mod that lets me assign key bindings. I have just started to tank so have people dps the right things would be a help (and yes i have had to deal with the people that are like go go go, and we die cause of them ).
