This is total nonsense. Like the guy/girl who created the video, I find myself in a similar situation, I have seenthe game changing and I tried to adapt to many of the changes introduced. However, when you change things so deeply over the years, you will always inevitably lose people and gain new people due to the age of the people playing the game, and also because the game isn't what it used to be. This is OK, as people who started playing more recently will probably say the game is fine and disagree with "older" guys who preferred the old version of the game.
What the author of the video really is hinting at, is that he has nobody else to play with due to the way the game is nowadays. Which is exactly how a lot of us feel. Even If the game changed so much, If I still had a lot of my friends playing it I would also still play it, but the reality is, nobody but myself was playing it before I quit.
I hope it makes sense?
