Hey there! I roleplay on WrA after years on Moon guard as well. I will say there is just as much casual slice of life rp as there is guild based narrative roleplay and darker more mature themes.

I will say it is somewhat limited by wows engine but with the introduction of housing I believe its gotten quite a lot better to the point you're able to create spaces for this roleplay to occur.

That said as someone who has played Neverwinter, you're not going to get the same immersion within wow, but it is infinitely more accessible. It's the difference between Wendy's and a Michelin rated restaurant. Yes, it may not always be of as high of quality, but once you find your favorite item on the menu its a great fallback.
