Unfortunately the majority of 5e that I have played was in adventurers league, where all that non PHB content isn't allowed for one reason or another.<br/><br/>The non AL league game i'm in i've been playing a barbarian and haven't had time to switch.<br/><br/>But I think the mystic looks pretty fun. You get a lot of options on how to make your mystic, which I think really makes it nice.
