If you want to change something be prepared to make the case for it, that's all I say.

I'm open-minded about these things. I'd sooner have an active Green Lantern Ben Grimm than an NPCed The Thing. With that being said, I'm equally as open-minded about retconning things out of existence should they not work out. I'll accept changes if and where they work but I think it's unfair for other people to have their hands tied by them when they do not.
