I use Action Bar Profiles (Saver) for switching between PvP and PvE. It also supports switching out talents and what not. It still works on retail for me despite being for 9.0.1.

This is probably far-fetched.. but I was looking through Grid2 trying to find a status similar to what BattleGroundEnemies offers in terms of showing how many players are targeting a particular player. I think it'd help a lot with seeing who the enemy team's kill target is during a RBG (for healing purposes). Is anyone aware of a way to replicate that functionality with Grid2?
