Fellow Lancer homebrew creator here. I love Vertrung! I think it has a ton of super interesting ideas, plenty of wonderful frames and pieces to mix and match, and a ton of content to make the purchase worth the money. Some things are a bit unbalanced, but changes are still being made and I'm sure those issues will even out. Overall this does the most important thing a homebrew can do - it occasionally makes you think "how did I live without this?"
