No, people play everyday. Those are just the scheduled “Raid” times. And no, you can make a character and then join a guild. A lot of people play other games together so know they will be playing together. For example our guild. We’ve been playing together over a year and are coming back to kill Classic. If you’d like to check us out feel free to look at our thread or hit us up for Discord info. Cheers and enjoy the game!
