Honestly the people complaining about the game should seriously SHUT THE **** UP.
Simple as that.
I've said it before and I'll say it again, your statement is the cliché argument against people that have something negative to say about a beta product, I would like to think that most people here are mature enough to provide constructive criticism, feedback has been pretty elaborate, particularly when people have quote, unquote negative feedback. And I'm sure that the devs appreciate criticism in such a fashion and are also smart enough to ignore any of the "this game sux" comments and are equally aware of the fact that people are a lot quicker to complain about the negatives then praise the positives, that's just human nature.
The more feedback the better if you ask me and not mentioning something because it's a beta seems even more ridiculous, if we don't make comments how could the final product possibly be improved upon. It is also a consumer product, we are paying for this, ISI is not a charity and if people have something to say about the product they are buying they should be entitled to do so in a civilised manner!
Oh and telling someone to Shut the **** up is utterly rude, obnoxious and completely does away with any validity that your argument ever had. I much rather here a well constructed bit of feedback then the type of language you are using even if you tend to categorise feedback as complaints.
