Welcome back! A lot has been added since you have been gone and a lot has changed as well. The new regions have level caps to prevent the advantages of story sweeping so you may need to level some new friends through the regions.
As for hand holding, the forums has some pretty fantastic guides - Everything is pretty much documented, everything from every learnable moves and where to learn them all the way to full regional guides. The guide tavern is wonderful place. Also, the players in game will be happy to help you find something. If you ever have a more technical issue, we have an amazing staff who are always ready to answer you questions. Well anyway, I hope to see you out in game!
