IMHO - Arthas was handled poorly in WoW. He was an icon because of WCIII, so he already had a string following (including myself). But the constant "I'm popping in every once in a while to tell you....I'll get you later" was overdone and made him lame. In fact, Arthas appearing all the time was one of the major complaints in WotLk. As always, Blizzard swings the pendulum too hard to address player concerns, and that is why Deathwing seemed so "missing".
That's my opinion anyway.
