Here is another addon similar to AVR and AVRe. This time it uses your in game map to display the information. It looks very interesting by the videos, I plan on playing with it Wed Night.Heroic Sindragossa 10Man25Man Blood CouncilPlague Wing
<- My Personal favorite example
Keep in mind most of these videos have AVR+AVRe running in the background, so I think it makes a good comparison.
Also, Blizzard has already been asked about them intentionally breaking this mod. Here is what they had to say:
Is this addon going to get banned because Blizzard doesn't like AVR?
To head off the inevitable, I've asked Blizzard if this is kosher in light of the AVR breakage. They have not indicated that it is a violation of the rules. Until they indicate otherwise, HudMap will be developed and updated. The impression I get is that Blizzard's primary complaint was with AVR's ability to draw pseudo-3D images over the game world, which is outside of the scope of what the UI was intended to be able to do. HudMap doesn't do any of that.
It certainly looks interesting, and could be some good help for everybody.
