I have a blind friend that plays World of Warcraft. His character name is Refunki. You can see his armory here:
Another thread about problems for the blind here:
And his Youtube account, showing he is blind and playing WoW:
For years now (since the beginning of Cata), we have used scripting commands and voiced emotes like /yell, /cheer and /roar to communicate with him and other players. We purchased a Vent server so he could talk with guildies. He has a macro that he sends to players in battlegrounds letting them know he is blind and how he will contribute to the battleground. He is consistently in the top half of DPS in random BGs when someone leads him to the fight. Playing World of Warcraft has been the first time since going blind that he has been able to play a video game, and it has brought him many friendships and immense satisfaction.
Breaking /follow in battlegrounds effectively prevents blind people from playing. He literally can no longer play and it has made him depressed. It is just one more way the world around him refuses to welcome him into doing regular things that all his friends do.
What's more, I am shocked that Blizzard, after touting the success of another blind player
(http://wow.joystiq.com/2012/01/12/guide-dog-player-and-guild-embrace-sightless-guildmate-steer/) would do something that would so fundamentally prevent a blind player from playing. I was encouraged that I could play with my friend for years to come.
Refunki is willing and able to provide documentation of his blindness, if only he can play again. Please don't punish him for the actions of others.
Edited to clarify.
