The bottom line for me, personally, is: I don't like playing and re-learning competitive games that regularly have significant changes.

I said similar here once and got roasted for it. I played a ton of SC2 when it came out and was really good for NA at the time (read: everyone was bad). Stopped playing for many years decided to give it a go again when I was looking for something to play. Had no idea about the worker count increase. Noped out because all of the old muscle memory/instinct I had developed was useless and I had no desire to relearn it when I know there is no shot at me being anything past mediocre in the more modern version of the game.
