Why? So that the poor people who are making others miserable can still enjoy themselves? If someone is being an ass that griefs and insults everyone around, they should be removed for the health of the game and the atmosphere in it. "Providing tools to deal with the situation yourself" is just pushing the effort on the victim.
There are no bugs in WoD leveling. Treasures and objectives give decent exp by design, and with a flying mount you can just level off of them. No glitch there, obviously.Edit: The common sense argument really doesn't make much sense when you consider that power leveling through those world side quests and going through 5 levels in draenor in under 20 minutes wasn't an bannable exploit. "You had to do a workaround so it's clear it's not intended" except, I also need a workaround to get voice chat to work. Why would someone have any reason to think this is different?
Voice chat is outside of the game, so it's irrelevant.
The xp glitch was obviously a glitch, and arguing otherwise is just a brain exercise to defend cheaters. Don't do that, you may think it's noble but it's not. It's like arguing someone was allowed to destroy public property because no one told them it's illegal.
