My Idea for how I should approach building my war base

I’ve been struggling at getting information on war bases and a lot of sources aren’t very helpful to me and don’t give detailed information about the building process of a war base. Some of these sources only talk about their war base and why they designed it that way but they don’t cover where to start, where to place defenses, how to set up compartment and what buildings to put in them. But some sources have some info that I want or needed to know but I eventually found out after taking some notes these sources are like 3-5 years old and a lot has changed since then making the info I gathered useless. Because in 2019 they added 2 more th levels meaning more troops and it changes the gameplay and how we defend our bases. I did find 2 videos on YouTube with only one being helpful for me and my th11 base because the other covered th9 war base layouts but it didn’t have much detail. The next one was like a video on the fundamentals of war bases and covered many things including trap placement and how heavily it effects how well you defend against attacks. Here is all the info I gathered some outdated and some not:

I think most of my struggle was not just building the base but because of the releases of th12 and 13 last year people focused mainly on them so there were barely any th11 specific sources. then I thought of a solution that may help me break down these bases a lot easier, and that is to try and find war base information on lower town halls and try to climb my way up to making More advanced level war bases. Since I have a th6 account it may be the perfect starting point to learn how to build my war base and may actually teach me a round about way to approach the building process, design, and strategical placement that comes into play when building a war base. But I also have a back up plan just in case this ends up being a waste of time. So stay tuned if you want to see what I come up with next and if you want to hear my plan B option.🐓
