Legion pre-patch (and hopefully legion) has brought a lot of great or interesting changes. However there's one change that's the worst of them all, making the game nigh unplayable and shaking my faith that legion will be a serious step up from Warlords of Draenor: the minimap rare elite indicator (brought in for Mists of Panria Rare Elites) has changed from a sick skull to a shameful yellow star.
Fortunately, I spent most of a day both solving this hideous atrocity and making an addon to share with benevolence to the wider World of Warcraft community fixing this travesty.
For those wishing a technical explanation, there's confusingly two image atlases used for minimaps:
Interface\MINIMAP\OBJECTICONS.blp
Interface\MINIMAP\ObjectIconsAtlas.blp
ObjectIcons can be overwritten in your Interface folder with a blp or a tga but it doesn't do anything. ObjectIconsAtlas is what the minimap uses but it cannot be overwritten. However the fix to this conundrum is this a single line of code:
Minimap:SetBlipTexture(FILE_PATH_HERE)
So using this single line of code I made an addon and using images from google and significant help from this blizzard image library on github:
https://github.com/Gethe/wow-ui-textures
I recreated the ObjectIconsAtlas and placed the skull icon back in its rightful place.
You're welcome : )
