Are There Plans to Fix Aggro?

I never played retail so I can't compare other than to many other realms on Molten/Warmane for which I have played almost 5 years and thousands of hours. It used to be possible to sneak by mobs before that are impossible now. It used to be possible to single out or only risk one possible add in a given fight. Now I see people running in front of me so I have a better view of the distances involved and it looks like mons will pull from as far away as 50 meters or more. The range seems to increase if you attack one of his buddies. I have seen mobs run 70-80 meters to help a buddy and often this means you will have 3-4 mobs on you and you're dead before you even have time o react because they come from all directions.

I have the script that doubles the Zoom Out distance. It goes so far that when in some instances Zooming Out will take you out of the building! Even with that distance I see mobs aggro that were outside my POV. It's not the biggest issue of all but it surely is annoying and seems just wrong. So what's the deal? Is this permanent or not?
