You're not seeing it the way you should: as constructive criticism that may help you and your team improve and be more professional.
And sorry, but I do have truth in what I say. It is not something I invented. It is something most web designers with at least some basic knowledge on what design is supposed to be about, and on creating user-friendly websites and web applications (for developers here), understand and agree with.
I do have a flash plugin installed... isn't that obvious if I was able to access the website? Yes, there ARE people without flash plugins. People who have old systems, people who just bought their computers, people with OUTDATED flash plugins, and so on. And like I clearly said before, a flash plugin isn't precisely the only reason for which an animation may not load.
Flash is meant to be used in websites with dynamic content, meant for greater interaction than just "point and click". Game presentations, for example. It's okay to have some portions of your website in flash, but not all of it unless it's quite necessary. If you really, really want a flash website, then try making some more use of it. I don't know. More than animating transitions between one page and the other... It's your website, just think of what you'd want to do.
And this is the last time I post here, because all of this is just supposed to help you out. If you don't want the help, then that's fine. But try not to close your mind to improvement.
See you.
