What char is best for boosting?

[Zafo]

I do 10-45 with an 80 frost mage 3 pull sfk, single pull armory and cath, you'd probably be better off doing the lower levels with a lower boost char for more xp though.
45-60 with an 80 blood DK in scholo clearing to before the whelps.
61-66,67 I boost in Ramparts with the DK then pretty much quest the rest of the way.

1-60 Takes 8-10hrs with RAF.

What about just leveling the DK to 60? Im sure i can get threw rfk sm and strat right? i can quest 50-60 cuz WPL and EPL is amazing quest exp
