Why not remove BT attunement?
Several Illidan farming guilds (alliance side) have already died because the lack of BT-attuned recruits. Most of these guilds have been farming the content for several months and can't be bothered to fill an entire raid to run through all the t5/t6 raids to attune just a few people with no guarantee that they will actually last.
Why not just remove the BT attunement as well? Would anyone actually care that it got removed? I know most of the remaining Illidan farming guilds wouldn't care at all. It would provide a much easier option for these guilds to keep up with the turnover which is the primary threat to these guilds survival.
