Rumor confirm/refute: Deleting battle.net cache to aid with FTJ Someone on b.net who I recently friended said that a possible solution to help with lag and Fail To Join issues was to purge the battle.net cache. I took his advice with a grain of salt since deleting anything someone on the internet tells you to delete is a brilliant idea /sarcasm Is this true? Could it possibly help? Would one delete the entire folder's contents or be selective? Is it dangerous to attempt? What's the deal, yo?
