Oh aye. It's been out for about two weeks, now.

It's a lot better than Factions, methinks, and brings back all the fun from Prophecies.

The Heroes are a very good idea - rather than have to spend so much on yourself getting al your skills together and changing professions and whatever, you can make your Heroes special builds instead, and you can actually tell them when to use the skills you've give them (they have every single skill you've unlocked in any of the games if you have them installed).

Also, rather than having to warp to the desert to change profession, you can do it in the Skills menu, and also save different builds that you can switch to by selecting them on a menu (however, you can only change them if you have completed those quests).
