At 98 you have the option to drop what you're doing and return to your capitol city to start the quest for your Legion Artifact weapon. However, I do not believe this is necessary to do right away unless you're struggling with kill speed in your current gear. I would recommend waiting for a natural pause, such as hearthing to repair and clear your bags. From 100 to 107 you won't even really fight mobs that often; only just enough to clear the way to any treasure you need to pick up.

I had multiple people ask me why I didn’t do blood or prot for leveling on DK/Pally and the god honest truth is the fact that I know how to play ret and unholy quite well and the limits of the class. I tried leveling as prot and good Christ it felt like I did no damage. If you take selfless healer and wake of ashes you should have 0 issues with leveling as Ret and it is significantly faster. As for Unholy if you take grip of the dead to kite a little, deathpact for healing, and keep up with your Dark Succor (spelling?) procs you will have no issues. I died once as DK and none as pally. The only classes I struggled with a little was WW and Shaman. WW because the aoe felt under-tuned at the time and shaman because they are trash imho.
Third: Do Warfront when you can (if they open for the first week which I haven’t read anything that says they aren’t) because it gives a 370 piece of gear and gives you access to Arathi Highlands where you can kill a world boss and do quest for rep. They did remove the 355 drops (despite what Preach said in his last video, I just went and checked it before typing this up) and they only drop 280.
