Hello, and welcome to the RP community of ESO! I'm glad to hear that you're enjoying the game so far. I personally have been playing ESO for about two years now and I personally have enjoyed the content and the community here regardless.
And you are right in your observation of the lack of public roleplaying in the game. RP still exists in ESO, but it is very much focused on individual guilds, not some much on hubs anymore. Between phasing issues that emerged from the One Tamriel patch (which more or less saved the game from dying a slow death), player housing, and occasional drama, the public RP scene save for a handful of locations is dying. However, guild RP in ESO is very much alive and kicking. And if you ask around for suggestions, I'm very certain you'll find the RP you are looking for.
I'll be more than happy to answer whatever questions you may have and help you along the way. Beyond that, I once again welcome you and wish you many a fair adventure in the land of Tamriel.
