Most of us have been playing this game for years.
I personally started this game a couple of months into vanilla. Choosing a realm was easy, I just went with what my friends were playing on, which was a medium/high-pop realm. Seemed fine.
I'm pretty sure this is how most of us started out. You pick a realm, based on the population, and the people you play with. Most people want to play on a realm that alredy has a high population.
Very few of us actually started playing WoW the day vanilla was released. Imagine having to choose from 100 different realms. All of which are by then, completely empty. You have no idea what to pick, and you have no idea if your realm is gonna end up being dead in just a couple of hours or if it's gonna be a high-pop fantasy.
Now, I'm expecting WoW Classic to be an even bigger release than vanilla was. Millions of players are gonna be ready to play, from day one, and start out at just this; Completely empty realms.
So, how are you guys planning on picking a realm? How to not risk ending up on a dead realm? We can't be sure to get realm-transfers early on in the game, if ever even.
