That's not even true because equally magical could be a 0 joining rate, which would make 100% retention meaningless. Also people die. Retention should still be divided into new and old player retention.
So, he's not a true Scotsman, eh? Retconning initial conditions doesn't make your original assumptions any better. It just gets us into an endless loop of "Well, if we have this condition, too..."
Smiley faces are obnoxious.
Deal. We all have to put up with stuff we consider obnoxious.
Is it difficult to read quoted posts? I was replying to a person who specifically asked me what the problems were.
You didn't quote anything. It's pretty silly to try to slam someone for not reading your quoted material, when you don't quote anything.
And I know what you were replying to. I was acknowledging the fact that the problems you listed are known to the dev team. And that the four problems you identified are really only two problems: Finding new players, and retaining players.
