My current main grp is an aoe based group. I have a prot pally, disc priest and 3 arcane/fire mages. It works really well. I've run instances with several different groups and this is the easiest and most effective so far. I'm only 60 with them so no tbc experience. BRD was good for me to compare since I've struggled before in there for example with the groups of 3 fireguard destroyers outside the entrance to MC. With this grp It was a joke. Just run in and waste them...wasn't even slightly challenging.
