Hello, Andrea!
Thank you so, so much for the feedback and directness. For a small creator like me, an insight such as yours is gold.
I'm working on new rules for the 4th edition, basically rebuilding everything from scratch, taking in consideration all the problems you've pointed out and making many other improvements. Right now, I'm playtesting the rules as I build them. If you're interested in keeping up with the project, I suggest you check out the official discord server. The link is in the project page.
Again, thank you!
