Feels like that is likely really.
Retail crz could have been copied with woms work to fit here. We all have the common “legion” code base now. I mean we even have retail tmog. which is funny. the one class that rules allow tmog of illidan glaives…isn’t even in game yet. that will work day 1 of legion classic if reached lol.
X-realm all, even OCE. I started oce in retail. Only seeing 200 OCE logged in, not a big deal. I am seeing 1000’s of us peeps easily.
Same for retail universal AH. that is how they fixed dead AH on slow servers. they now see the fine offerings of Illidan, A52 and retails other massive pop servers.
