It's all getting kind of unimaginative
This is why we've never seen the blue before. Natural selection. They just don't last too long.
And I'm just going to say it: Johns still hasn't convinced me there's any kind of loss. The blue are just so...INSIPID. I have a hard time thinking only the yellow and green wielders have full personalities. The other rings have the AMAZING ABILITY to allow Johns to write totally one-note characters.
Also: Hey blue lanterns! Be useful! Go to more dead planets and restore them! Or do you only do that to impress Jordan?
I'm serious. The thing is, their use doesn't appear to be COMBAT. I think it's a little silly that, well...all these rings with all their particularities, and they ALL use them to fight? Seems to me the Blue are better used like medics or chaplains, as one example. Or like the Army Corps of Engineers. Or FEMA(if it was effective).
