That's kind of the same sort of weasel-wording that we had in the other thread about the roadmap.
"Because there's THIS thing that can fit in an overly-broad application of a word, we can use ANY thing that also fits there and it's just fine."
I don't accept that. Continuity, IMLTHO, is very important. For instance, it's not out of place if there are radioactive zombies. Why? Because the lore sets it up that there were nuclear elements to this holocaust and they even use radiation to set the borders of the map. Meanwhile, super-zombies that are tanks and also somehow came to be wearing suicide vests don't have that benefit. They're being RETCONNED, and the only explanation is "well, we have this one occult thing, so adding magic-wielding liches are fine too!"
PS - yeah, I think we're even now.
