All that happened is that Thor's role in the plot happened to be more limited, because of everything else happening. Loki still was the main villain, still played everyone like a fiddle, and Thor still got to kick ass.
Vampires, especially non soul less as Angel and later Spike are just humans that gained super powers and are fighting not to lose their inborn humanity. It`s classic. Thor and Loki may not be gods in MCU (they do not tire to remind that they are -advanced alien spiciest) but they not born humans no matter what powers they have and how long they live - they are different on a basic level. If MCU was willing to go full mysticism they are just as alien to humans(if not more so) as Illyria, but divinity and it`s exploration is a big "no go" in MCU.
