I am delighted you are continuing with this project

As I said originally, you have a nice writing style. You present the information clearly and come across as very approachable at the same time.
I think new players reading the guide will appreciate the fact that you aren't afraid to admit to making the odd mistake now and then. It is going to reassure them when they find themselves struggling with some of the harder aspects of the class.
Truly exceptional players often don't remember what it was like to be a beginner or never really found things difficult at all. It's hard for someone like that to help a person who is struggling because they are not going to understand why.

Some people might feel uneasy when someone writing a guide or trying to teach something admits to not knowing everything. To me that says you can honestly assess your own knowledge and you don't have ego problems. It also suggests you are the type of person who will constantly reassess what they know and continue to learn and improve.
I have a lot of respect for the way you have handled criticism as well, discussing the issues raised, taking suggestions on board and making changes.

I've bookmarked this thread and will be coming back regularly. I'll also point any friends who are starting Arcanist in this direction.
