@wildvine: Depends, if you're referring to a Grim Reaper type personification of the concept of death I suppose that would need to be an exception since people can still die here but if you want to use an actual mythological death god then they'd be under the same restrictions as the rest.
@delphic: Sorry, had an idea that wouldn't work unless I freed them up, tho its only 7 potential characters that aren't restricted. Its not all angels that don't need Avatars, any that aren't Seraphim have the same restrictions so you can still have an angel stuck in Avatar form just not those 7.
@rbt: I didn't think it was terrible, I just think they spent a little too much time focusing on establishing the universe. The League storyline could have been way better if they'd given it a bit more attention.
@cbishop: if you want you could have a character who has figured out their identity and is piecing together what happened to them.
Or you could write from the perspective of one of the Seraphim who can freely travel to Earth. I'm using Michael and Gabriel but the rest of the known ones are free to use or you can make one up I suppose. Not really sure about how many Seraphim exist in Judeo-christian mythology.
I've noticed a lot of people were down on Arrow this year and I get why. I think the main reason for this is the same as why people were so down on Iron Man 2, it seemed more interested in setting up the next thing than it was with the story at hand.
