It wouldn't surprise me. At all. What the hardcore players want is a sanitized, samey experience so they can show off how good they are at hitting their parse! And if all the jobs feel the same, they can reroll classes! But keep some classes really low DPS. Easier to lord over them and be superior that way.

God forbid we have any variety or feeling in classes. It's pretty bad when World of Warcraft can show you up.
