People leave because they are unhappy, simple. If they were happy, then the numbers would tell a different story.
I agree, personal opinion do vary, and some people complain about everything. However, when so many people complain about the same things, then isn't that more of a trend, and therefore indicative of what life may actually be like at FZ?
It may be a personal opinion, but it's an opinion shared by many. If you join and don't expect much, you wont be too disappointed.
