I'm search for an addon that shows mobs in an unit frame for example like Grid. I think it could based on your own aggro from each mob who has aggro on you. If that, the addon adds a new "mob unit" to the mob-UI. So I mean: mob-aggro on you - one mob unit, other mob-aggro on you - second unit frame, and so on. I don't mean that only mobs who's aggro is "completely" on you would shown. You know, if the tank pulls a mob group, every mob in this group had percentage aggro on you whether you're the tank, dd or heal. Therefore every mob should shown in the "Mob-Aggro-Unit". As I say - all based on percentage aggro.
If that would be possible at all, the "mob-units" must be clickable. Simply it can be done by an other addon like Clique, but for that, the addon must have the possibility to do it, you know.
If that would be also possible, it would be great if you have the possibility to show debuff icons on each unit, again like you can show buff or cast symbols or icons in Grid. Optimal it would be as high configurable like Grid.
I don't think that an addon like this already exists. If you know one or at least a similar please tell me. Otherwise it could be a good idea for a new addon.
Link to the Grid addon maybe show you again what I have in mind. Maybe you know the Gladius addon for pvp. Similarly the addon does what I mean but only for pvp - if it would show mobs also - we have it.
Update: After a few days of searching without results I find out that I'm not the only one who had this idea - strange It seems that the only reason why it's impossible to create an addon like this is that Blizzard not allowed to click on the mob frame in fight. It gives a few attempts like PVEFrames (link below) but they are outdated, buggy or do not what they should do. I really wonder why Blizzard don't gives the possibility to click on mob frames, they allowed it in PVP and I see no reason why it's "forbidden" in PVE. It would just makes life easier in the random mob fights without giving any forbidden advantage. I'm with efindel - maybe Blizzard will change there restrictions in the future.
People have been asking for this for a long time, but it's not possible under the current restrictions Blizzard has placed on what addons can do. If it ever becomes possible, you can be sure that someone will make it quite soon thereafter, given the number of people who want it!
