That's unavoidable though in terms of them being separate social areas. Possibly there will be vendors that are universal. Master rahool is one of many cryptarchs for example. Not a stretch to think there would be another one there. Might be that there's a lot of daily reef bounties so you wont be able to carry all of them as it is. I don't think there would be a vanguard presence at the reef, that wouldn't really make sense.
