TIL sharing raid lockouts for older raids is considered an exploit!

Accoring to a GM it is against the rules to share lockouts between you characters to skip bosses in old raids.Have been doing this for years but today i was contacted by a GM.Conversation with GM: http://ift.tt/2EcOZFd The titel is now incorrect since Araxom made it clear that this is infact not an exploit. ThanksEdit 2: Alot of people have been asking why the GM contacted me. He contacted me after i submited a bug report regarding Mogu'shan vault lockouts that since 7.3.5 has not been working as intended. I also created a ticket regarding the bug. This is the link to the bug report: http://ift.tt/2DDsJTQ 3: The original ticket was reopened and i got a great response and support from GM Xanaverr in game. He told me that this is infact not an exploit. Credit to this guy for great customer support. Also, thanks again to Araxom for the quick response on this thread.Edit 4: The Mogu'shan vaults bug that started this whole thing has not yet been fixed. Since 7.3.5 i have had alot of struggles with my raid lockouts.
