Going to piggyback off Sarestha here and also encourage you to check out the forums, Discord, Tumblr, and other social media so you can be aware of all the public RP events going on every week.
Wyrmrest Accord Social Hub Discord
Warcraft Neutral Events Discord
The above also maintains a community calendar!
And then there’s Tumblr pages that do nothing but post and repost events.

I’ve been playing and RP’ing off and on in WoW for a long time, but the past couple of years of diving deeply into RP, doing all these events, and getting to run into the same people in different places has been the most fun I’ve had in the game in a while!
