1) new race
2) new classes (Ritualist and dervish from guild wars 1 would be awesome)
3) new zones
4) new legendary weapons
5) maybe not in heart of thrones, but in the future I would like seeing maybe legendary armor.
6) I really miss the henchmen/heroes from gw1. Obviously don’t have them for just roaming, but if they were there for dungeons and storyline missions I think it would be useful.
