So, just returning from a bit of vacation and back to working on leveling my various toons. I did manage to drive the mage into Northrend before leaving for vacation. Since returning, I was able to get the Shaman a little further into Outland - from level 64 to level 66. I've now gone back to working on the Rogue for a little while.
Since the rogue seems to be squishiest of all of these last four toons, I'm working on trying another questing path through Outland - at least for Hellfire Peninsula. I've always hit those demon camps up above Thrallmar pretty early on in Hellfire, and while it's doable, it's probably not the easiest approach, so I'm going to work on hitting Spinebreaker and Falcon Watch a little bit earlier and maybe come back to the Forge Camps later on. We'll see how that goes. I will probably work on the rogue until the early part of next week - likely won't actually get him all the way through Outland, but maybe a few levels.
