One thing I struggle with as a complete noob is the subtle nuances of node types. Things like a reference to a player character vs a player controller or why self is OK on some nodes, but not others. I now get the difference between an actor and a component, but that was confusing at first and took some trial and error to understand. I think a reference guide to all nodes is probably a big task, but would be super useful for beginners.
I’m still a noob and don’t fully understand a lot of what I’ve done that works, but I’m getting there. I’d highly recommend these tutorials to anyone still learning the basics. They did a lot of relatively simple stuff in the most stripped down way, but you get the basics and can then extrapolate and start to learn a lot on your own.

There was also a link in the forums that I can’t find now, to an e-book with a good tutorial that filled in a lot of blanks for me. I’ll try to find that link when I get home to share.
