Galactic challenges were supposed to be new content. But they are really the stupidest part of the game right now. If I did not have to do them to progress I would choose not to do them. They teach me nothing about the game except that it can get stupid hard when a dev turns the levels up. So what?
A major problem with the game is we don’t get to actually practice what we do. Galactic challenges don’t help that. And they have devolved into pay walled products I won’t buy.
