Legion items look pretty epic, you need to go to /shadowfall and buy the legion armor for 1,200 adventure coins then you can buy the other legion items and go on the quests. Besides that, you can use a trainer for AQWorlds to get reputation to get classes. Don't know how long you've been away, but 8v8 PvP is also pretty entertaining. I'm sure you've missed out on a lot of the story also, there are only 2 more chaos lords to go.
