Lich King is weakening, so Arthas travels to Northrend to help, while Sylvanas gets autonomy. She’s a one-trick-pony, even if the trick is very powerful: Possess. Still, I can understand the sexy zombie appeal.
There’s a certain power creep. In Reign of Chaos, maximum hero level was 10, and so was the maximum level of the creeps. Now you get creeps up to level 15, while Arthas gets downleveled every mission to represent Lich King getting weaker.
Still, the missions are some of the easiest in both campaigns. As Sylvanas, you can mass frost wyrm, while Arthas gets three dungeons one after the other. I completely forgot there was a Chtulhu themed Forgotten One.
I remember the last mission as very chaotic and frustrating. I think they’ve changed the map, but it is still annoying as hell. Not sure if in the original AI was as efficient in countering, because when I went frost wyrms, it massed the naga flyers, so I had to wait for Illidan to start channeling to have any chance, otherwise it becomes a complete mess.
Finally, Arthas duels Illidan and even wins, becoming one with the Lich King.
