Personally, I think this might actually be a good thing, this change could potentially give the game a much needed boost, which wouldn’t be possible under Turbine. Especially since Warner Bros. decided to make Turbine into a mobile gaming subsidiary.
And for context, Daybreak has published games such as Payday, Everquest, Everquest II, H1Z1, etc. So they’re pretty well established and this will help the future of the game (the Mordor xpac, etc.)
