Having more features, especially those aimed at corporations instead of indies, means it’s harder to figure out how to make simple things work, especially without tutorials. Even the things that could be simple are probably still more complicated than an indie engine in order to help large developers do what they need to. Since Unreal Engine is pretty much designed for Epic to make their games in, you can bet that that’s their first priority, and indies get table scraps.
The flip side of that coin is that you have access to a lot of the features that the corporations do if you want to put in the time to use them.
