Why not just an "isAimedAtPlayer" boolean then?
But for real. Isn't that just what they got rid of in that pvp addon? Why would you want something into that direction again?
Aside from that I feel the players should look at the world and telegraphs on the ground when an attack is incoming during fights and think and react on their own - not look at some popup notifications from an addon. It's part of the game to have to learn how to react to enemies. Reducing that to a reading lesson via an addon is wrong IMO. Combat addons should just stay on the sidelines and offer information that cannot be seen from the world (e.g. damage numbers and buff times). They shouldn't tell the player what to do. The game is already easy enough as is.
