I'd rather he lived because Anduin is the only other really interesting Human character besides Jaina. Right now, Alliance lore is dominated by the Night Elves (been around forever, know everything, have super awesome powers), which is fine, but if Blizzard is going to continue to make Varian out to be the centerpiece of the Alliance, there needs to be a reason for that. In Wolfheart, it looked like Malfurion and Tyrande had a far better grasp of what the Alliance needed than Varian did.
