I don’t know why you guys are freaking out about Savin taking over when it literally says in the blog that “Savin is only going to be managing writing commissions and helping him keep the details of the lore & universe straight.” It’s the same stuff he’s always been doing as a lead writer for TiTs (pretty much why most of the content is written by Savin himself).
I wouldn’t say Savin is going to take over the entire project, but more that he’s going to write the stuff Fen wants like the Myrellion quest Fen laid down for him and the other two.
Fen already said so himself that he’s going to be taking more of a producer role now, which means he is still head of his own project, it’s just that he will be telling Savin, Adj and Gedan what to do and fixing bugs. So, Fen is going to still keep Savin and the others in check.
That’s why I said that nothing is going to change, because it’s always been that way except Fen is going to make other people do his work for him. It’s not only going to be just Savin doing everything either. Fen stated clearly that “Savin/Gedan/Adjatha are all taking up some heavy lifting in the company.”
