They won't, because the scene changed a lot.If I were a top player who had voiced disinterest in KOTD4 over the last couple of weeks, this post would be a major wake-up call to me.
Back in the day, top players were mostly fans of the games. Super grateful when the odd sponsor would pump money in the game we love, so we can have some competition.
Now it's professionals, focused on earning a living, whether it's this game or another. Sure they try to have fun while they're at it, but there's a lot of focus on maximizing earnings. And that's aoe4 now. Of course there's nothing wrong with that, it's their career and how they sustain themselves.
