"If you don't like this aspect of the system, just change it. Sheesh."
"You changed hit points back to one die on 1st level? How dare you?"
Etc. etc. ad nauseam.
4E isn't really a big change from 3.5, you can easily convert your characters and campaigns and play as if nothing has changed other than some rule improvements.
