While most of the Podcast is speculation, as no plan survives first contact, I found it very interesting.
I especially found Lore's comments about his plan to level his Paladin to 80, and then explore the Death Knight, to be thought provoking.
I suspect that the initial 15 level disparity (with Death Knights starting at 55 and needing to get to 70 to enjoy WotLK content) will greatly thin the numbers of Death Knights to begin with. I recall 55 to 70 taking about 3 weeks, and that is a large down time in terms of seeing new content with the rest of your guild/friends. So, expect to see 1000's of created Death Knights at level 55, and only dozens of those players getting to level 56 and beyond anytime soon.
That said, it would not surprise me to see a large influx of Death Knights leveling from 56-80 about 6 - 8 weeks after WotLK's release.
Assuming all that we know now holds true, do you hope to have a Death Knight join you in the Podcasts, along with the mythical Druid Tank?
As always, thanks to Ciderhelm and Lore for the excellent level of work.
