I and many other blind players use range display in order to get sound notifications for range with friendlys or enemy’s in or out of combat, it is absolutely fundamental for our ability to navigate and play this game.
In 10.2 blizzard have blocked this capability during combat, combat being a major part of this game and its whole founding point, blizzard have come in and cut our canes in half! Imagine if blizzard cut your viewing distance to 1 yard and you had to navigate combat like that, annoying yes?!
What annoys me even more is that blizzard block things like this knowing full well that people need it to navigate the world but they offer no inclusion of a native solution, how about you add a range notification system before cutting people with accessability needs off from it. Please add this function back to wow until such time that you supply your own native solution.
