Hi and welcome to these forums!
First and foremost - well done. It takes a lot of time, effort, and generosity to be willing to write such a comprehensive guide for a gaming community. For that alone, you deserve praise and gratitude.
I have read the first 10 pages. I only managed to briefly scan the rest and review your chapter titles/table of contents. It appears you cover a lot of important topics and strategies - well done.
My first piece of constructive feedback is regarding advice you give to on page 6, under The Basics. You state “Aim for the perfect game, try not to die and analyze as much as possible.” Overall, I appreciate your strategical approach to the game. I agree that mechanics < teamwork/strategy. I do take issue with intentionally trying not to die. If a newer player reads that, it can encourage very passive play. Unless you’re on a team full of passive players (and you do mention turtling later, which is when this may work), a Ringo who is scared to engage because they want to avoid dieing, or a captain who disengaged too early due to fear of death - it really hurts the team and can cause you to lose a team fight you’d otherwise win. On many occassions, being aggressive in a team fight, even if it leads to your death, can do enough to help your team win the fight.
One small bit of contradiction is when you mention the importance of last hitting, especially as it relates to the importance of laning. That statement in itself is very true and I coulnd’t agree more. I personally consider last-hitting a skillful “mechanic” of the game, and a mechanic that has great importance. So, while strategy is very important as you mention, so is last-hitting (but you state strategy is more important, then go on to state how important farming and gold is to laning - which in itself is a stragey, but one that requires a good mechanic to successfully complete.)
Potential solutions: reword some of your opening statements on page 6. Perhaps encourage captain play for new users (generally, they’re harder to kill any ways) and staying with the team, focusing on healing. I find I can observe a lot about other junglers/carries when I am playing captain alongside them. I can pick up rotation tendencies, item builds, etc. Perhaps encourage better positioning (stay closer to your tower, stay behind your captain, etc) rather than just stating don’t die.
Finally, rather than a big blanket statement of strategy > mechanics, perhaps elaborate and make it a few more sentences. What strategies are important? What mechanics are most important to master first to accompany those strategies? Or, simply reword to say something along the lines of “the team with the best composition, rotations, and teamwork will always beat the team with less coordinated but more individually skilled players. Therefore, I recommend prioritizing learning the meta and overall strategies to a MOBA game over the mechanics”
I hope my feedback is helpful for you. Thank you for this great contribution to the VG and MOBA community! I look forward to reading the rest, and overall, I really enjoyed what I read. You break down laning as one should for those who want to become more competitive MOBA players. I appreciate the time and effort you put into this.
EDIT: While I haven’t gotten to this part yet, I love the fact that you have a section/chapter dedicated to “mindset”. SUPER important in MOBA. I often feel a player or team wins or loses the game before it even starts based on their mindset. The “I need to carry the team this game” often leads to quick tilting, tunnel-vision playstyle, and a losing effort. I look forward to reading what you talk about there!
