I'll be honest hear, its not as bad as you seem to think it is by how you typed in the post. It's some good plays, good editing, and so forth. Other than possible better video quality (that actually might be a problem on my end) the videos are fine and flow nicely. The problem is, and why your probably not getting popular, because there are so many others doing the exact same thing. The reason you see a lot of montage and league highlight youtubers being famous today is because they did it when it wasnt popular at all, and was a new thing.
Think of it this way, your a small fish living in the sea. You see that there are larger fish, that seem to be fed well, so you wonder why. You find out they went to a new coral reef, so you follow along. But, as you are following, there are thousands of other fish following too, all near identical in size to you. They all seem to be swimming in the same direction, maybe at different paces, but never as fast as the big fish. There are also sharks, who taunt the small fish and tell them they are not as good as the big fish. When you arrive, theres no food because they big fish had eaten it a while ago. So, you decide to swim away, and stumble upon a new reef. This one has tons of food, shelter, and other things. Now you are a big fish, and everyone starts following you.
Everyone is making montages with plays, using the usually EDM background track and drops here and there. You might make it a little far, but you wont ever make it as far as big name youtubers. Sit back and watch some other videos, youll start to see a pattern. If you want to climb youtube, do something different. You dont have to switch immediately though, wait to build a fanbase and take the time to think about it. Think about what no one has done yet, or just something that hasnt come to light. You videos arent bad, it just takes time and a little bit of thinking to eventually decide what you want your channel to be.
