We may have a wording definition issue here. I've heard multiple definitions of "integration tests". I usually use them where some people use "acceptance tests", aka, top-down be-a-user type testing (selenium in Firefox, for example). Sorry if there was any confusion there. Agreed having a QA team also go through the app is great for finding things that tests can't catch, like usability errors, or crazy edge cases you didn't think about, etc. I have gotten to work with a good QA team and it's amazing the things they find.
