Anyone knows if there is something like that or if thats even possible?What that addon would do is list your targets that you are in combat(raid enviroment) with similar to what you have in battleground targets(list of targets-option to see who that mob is targeting)) for simple trageting.Possibley with option of blacklisting certain mobs on bosses.
-but i guees nothing changed on this part
"Note: The bars are not clickable. Due to the secure templates added in WoW 2.0, this is no longer possible. PvP specific addons get around this limitation by making macros that target players by name. Since NPC names are not unique, this is not a viable solution for Magic Targets."
so its not really useable for targeting mobs or am i wrong on that part?
If you're using it to keep track of bosses or adds with unique names, it works for that. If you're looking for something to give you clickable frames to target trash mobs with the same name but different raid marks (or similar), it won't work for that, and that's not possible.
You can easily show health bars for any number of mobs with the same name, since you can distinguish them by their GUID in the combat log. You just can't make them clickable to target the mobs, because there is no way to target a unit by its GUID.
Most addons I've seen doing this work by scanning your mouseover unit and the targets of everyone in your raid dozens of times per second, checking all of those units' GUIDs, and then updating the health and other info when they find a GUID they're interested in.
