Blizzard has proven the opposite to be bad. When they started prioritizing new players, giving handouts, and spending more effort trying to draw new players in than satisfying the current customers, that's when they lost a lot of old school players. Legion is the perfect example of what you end up with. A time sink Facebook game where you basically pull the lever on a slot machine and random gear falls out. Not what you need? Ah well just pull the lever again.
I'm new to Nost and Elysium, and have no problem starting at the bottom on whichever server they feel like releasing. The old players SHOULD take priority. They are the ones who lost everything they worked for. I didn't. I lost nothing, and currently have nothing to lose by fresh starting later. I'll probably end up rolling on BOTH.
In a few weeks when all the servers are out, this will be a non issue and everyone will be playing happily on the server they chose. It's gon b k bruh.
