Players on Blizzard's World of Warcraft forums have reported new bugs concerning the Mind Vision ability. Apparently, this skill cannot be used in patch 2.4.0 Arenas and it also cancels drinking potions.

Community Manager Nethaera discussed this in the forums. She said that Blizzard is aware that Mind Vision will not currently work in Arenas with patch 2.4.0. Nethaera assured gamers that devs are currently working on a technical fix for this particular bug.

Players out there had better be careful when using this ability to mark either Druids or Rogues in PvP. The use of this skill at the wrong time could potentially mean death for your entire party.
