Is this thread from an alt of the “stonetalon zone completely blocked off” guy?
My guild still does attunement runs. Just need to find the right guild.
The best time is after prime time, when most raids are finished and people are looking for something to do or are jumping on their alts.
Also about an hour and a half before prime time. Some people will try to cram in an attunement run for an alt so they can go to the raid.
