With respect to the WBH feats -I hate when ppl try to lowball instead of debating straight up- I'd just say in response that its only fair to raise his opponents respective feats as well. As I pointed out before, most of the Annihilators have survived planetary level destructive energy output before. Some have survived even more powerful forces. They've also destroyed planets etc on their own power as well. In some cases casually.
Norrin destroys a Badoon planet just as a lesson to his opponent basically telling him, "look dude, you can't beat me ok? Just give it up."

And just to prove beyond the shadow of a doubt that he did it basically for fun, I'll post the issue recap from Annihilation: Silver Surfer...
Then you've got Nova. I won't even go into the more recent stuff. A weaker version of Nova contained planet busting energies, inside of his own body.

I'm sure if I dig I'd find examples of BRB, Quasar et al doing similar things. The bottomline is its disrespectful to say that characters that have earned their stripes like those that make up the Annihilators would be melted by aftershocks from WBH.
