I have now hit 71 on both the druid and the hunter. The druid is operating out of Warsong Hold in the Borean Tundra and the hunter is hitting the field from Vengeance Landing on the other end of the continent.
My plan at the moment is to finish the quests in each of their regions and then swap them to the other end. Ideally I'd like to do go overland as I do it and collect enough flight locations to be able to have flight capability from one end of Northrend to the other. I'll probably work the druid some more this weekend since I want to keep his level in line with the rest of the guild.
As professions go the hunter's skinning is about maxed already. Leatherworking has made some progress, though it isn't yet to 400. Mining and herbalism on the druid have not moved much yet. Speaking of herbalism.. I'm really liking that little Heal Over Time you get from having your herb skilled up to high levels. I don't think it has been decisive in any fights yet but it has been somewhat handy when things get a bit messy.
