I just got out of a Flex wing 1 run, it wasn't fresh and started from Protectors. I got up to Sha and wiped on it twice before everyone quit. Now my question is if I start my own (I joined someone else's before) Flex group will I start from the first boss or Sha? I just wanna get a chance at my weapon (I play a ret and don't particularly care about the first boss or redoing the others).
I am pretty sure if you would start then it would start from Sha but if you join to someone else run or you make someone else to Queue who isn't saved then you will be able to get loot from all bosses you didn't kill.
