Super dumb comic and people are just swallowing it like cumshots while questioning a sundip all their lives like Superman doesn't jump 100 levels when he touches the sun.
That being said the draining Thor was capable of didn't even make sense. It basically turned into a no-limits fallacy with how it was shown. There's nothing to keep it in line which means it's perfect for the forums. Just created an awful character that may never appear again and if he does, gets jobbed out immediately.
