It would be very nice if Icecrown would offer the posibility of leveling in hardcore mode (1x, if you die, you need to restart).
The Hardcore mode would stop when you reach level 80
Everybody who wants HC mode would have the posibility to choose that when creating a lvl 1 char.
Automatically when they chose that they would join a guild
Reward for completing that would be a very rare mount, title and tabard
There are other servers who offer that (will not give any names) but the population is not the same as ICC and its a shame that ICC does not offer that benefit.
