Hey, no complains from me. Sure, it's a shame he's dead, he was a nice old chap and whatever, but it's worth it.... correction, it will be worth it if Kishimoto makes the characters react correctly.
I somehow think that Shikamaru won't start smoking though. I can picture something like this - Shikamaru with the cigarette, Kurenai sees him, slaps him silly and says something deep and insightful about Asuma as a human being, Shikamaru cries and quits smoking before he even started.
Well, as I said, I won't be sorry to see him go, but it would have been pretty cool if he had had time to do some extra-special jutsu and whatever.
