I would advise him to go to Grizzly Hills, it has great questchains and a nice Open world PvP dailyquest hub, an interesting concept that Blizzard has tried numerous times in Vanilla and TBC (where you had to hold bases in Nagrand). I will never forget the Tarrens Mill pvp battles, if you were a dot hexer back then, all you had to do is press your 3 macros and get thousands of HKs
