I know that with the new lockout system you can only kill hard modes with one specific raid ID. But what if, for instance, the first group I run with in the week was only doing heroic gunship, and I left the group while they did that? Would I then be able to come back into the raid after they down gunship and continue with their normal modes, THEN go with another heroic group, since I wasn't present for the heroic gunship kill? Or would it still not let me run with the second group doing heroics?
