Incase some of you don't read much on MMO-champion unless it has class color coded nerfs/buffs or pretty picturesWhen patch 4.3.2 launches, the PTR forum will go down and you'll then be able to find a link to the x64 client for the live realms on this forum.
When will patch 4.3.2 launch? I think Bankbutler said it well...
