personally, I left WoW for many reasons, I have little desire to use something that reminds me of it. If people miss it THAT much that they have to change their UI to reflect it, I feel just pity for them....

if it doesnt affect gameplay, not really sure how it would be an advantage for them. if automates anything, ban the lot. if you dont want to play and just automate, then you dont need to play and your character spot can be used by someone who wants to actually play the game, not bot it. thats the only reason I see to be concerned.
