I think something else to bring up is that just because you run 5 normally doesn't mean you can't drop down to 3 or 4. I would love to do some premade AB/WSG with, even a truncated, team. Even 5 guys 2 boxing and a 5 boxer would be sweet in AB. I used to be in a PvP guild (vanilla wow here) and the strats they had were amazingly effective and we won everything. I haven't had much luck with premades since, lol.
