Signs of Alien PQ coming back?

I mean the definition based on how they use the word in relation to how the content itself is thrown around.

At first it meant content that no other version had. Then when developers started to get bored they ported slightly nerfed versions of that content, and exclusive became "the version the content originated from". Nowadays exclusive just means "the version that has the unnerfed version of that content". Still pretty shaky though since there are exceptions. GMS has CWK as does SEA and EMS, but both versions that got CWK after GMS have MoNs with slots. Other than that, ThMS might have got visitor event first, but ours was unnerfed. We got to keep doing it after it ended as well as 10 att medals.

Isn't MSEA's Masteria and EMS different than ours? Aside from the MoNs with slots. IIRC MSEA doesn't even have HH and HH2 and only kept them for Halloween.
