I’ve successfully installed and started the 3.3.5 branch on my Linux server, since the documentation said, that it’s best for beginners. But what about the 7 branch? Is it stable? It says that it’s not for production, but I see a lot of stuff in there. Isn’t it ready?
7.x have nothing working speaking of Expansion content… Maybe TC is playable until 4.3.4 content… But starting from Pandaria to Legion there is nothing A.F.A.I.K.
Got it. As far as I see in Github, the main problem is the database, since we already have the game content. Too bad we can’t get it from Blizzard 
I’ll stick to 3.3.5a then. I won’t bother to look for “repacks”, since it seems, that the good people from TrinityCore are the only ones who are working on private server solution.
