This is exactly it, actually. WrA has more emphasis on guild rp and less on walk-up, through walk up rp is definitely a thing on the server! You just have to keep in mind time and location, MG is an east coast server and WrA is west coast, so our prime time is off by a few hours in comparison.
Also if you want to connect with fellow roleplayers I recommend the Wyrmrest Community Protect! It’s both a Discord and an in-game community that helps with meeting new people for walk ups and guilds for long term rp, as well as a handy calendar of upcoming server events.
