At first I tried to understand what stands for Akiyama and then I understood (if its the not the wrong understanding lol) that its the map. Mount Akiyama, right?
Nice looting guide and I see you're doing good with your video views and you're getting good watch times as well. In this rate, I think soon we'll get a new gamer celebrity in YouTube. Good luck.
And its true that using the same name as twitch may be easier to find you but I think you should keep the current name for the time being as you're already doing great having this name and this name can be your lucky charm as well. Besides, you can just leave your twitch channel link in your YouTube video description so that your YouTube viewers find your twitch channel easily.
Yes, that's the name of the map. I'll probably stick to the same name for now and then revisit the idea somewhere down the line. Thanks for the feedback!
