This walkthrough is a Work in Progress so after each gym I will edit this post and mention it has been updated.

Not to necro post or anything but I wanted opinions since I learned walkthroughs don't get closed I was wondering if people would want me to actually finish this walkthrough or at least attempt. So I made a strawpoll to poll opinions. I also you don't post unless you clicked the 3rd option.
