Homogenization. Mechanics and skills that were fine for years and years and years are suddenly a problem and get gutted, dumbed down and/or simply removed.
I know that point in the lifecycle of MMOs. The preview actually had me buy New World. Not because it's a superior game, but because it's one I haven't played yet and will therefore be fun until it isn't anymore. I'm not too motivated to play the newest iteration of my main class.
