Welcome back!
There are lots of great threads and resources available to you to look at that may answer of a few your questions. RP is abundant right now on both factions. If you’re looking for RP, I suggest joining the in game community that has a calendar for events and channels to find exactly what you’re looking for.
Find that here: [A/H] LFRP the In-Game Community
When looking for active guilds you can scroll down a few days to see all the active recruitment threads and look at the Guild and Communities Directory here: WrA Information & Directories - #26 by Reinore-wyrmrest-accord
If you have more specific questions or wants I’m sure the forum goers would love to help you further with their own suggestions and opinions.
