Few things:
1. Macros are okay if you're feeling lazy and doing content where you can be lazy (Fate farming, story fights, etc) - however the error you've made is in claiming that they're "competitive". As others have pointed out, there is an inherent GCD delay in GCD Macros (you can even see this in your own follow-up video) - a roughly ~5-10% DPS loss over the course of a fight. That isn't competitive, that's flat out worse, and the barrier you'd need to leap over to get that extra DPS is a very small one.
2. You mention that Monk "has a lot of buttons" but, in reality, it has very few. For example I can fit all my stance-related GCDs on Q, E, 1, 2, 3, and 4 - these are all well within range of WASD and make it very easy to execute any string of combos whenever I want on a standard USB KB+M.
3. While it's nice that you want to help players, a teacher is typically one with tons of info and experience regarding what they're teaching. You are clearly new to Monk as you've yet to even reach 60 - which isn't a bad thing, everyone's been where you are, but you shouldn't be spreading information you haven't verified with more experienced players or, alternatively, you can wait and get that experience yourself.
Also just some educational video editing related stuff:
- Don't need a face cam unless you're actually an important part of the video - people will have an easier time concentrating if the only thing they can see is the gameplay footage when they need to be looking at it.
- If you are going to include a face cam, don't put your face 2 feet away from it. This isn't flattering for anyone as it makes you look like you're breathing down the viewers neck.
- It's better to include ways to contact/follow you at the end of the video or at the beginning rather than taking up a portion of your screen throughout the whole video. Just makes it feel cluttered that way, especially when you have a face cam and a text document on it as well.
