You don't want people to complain in EA, really? You just want "positive" feedback? What if multi-crew takes years? or AI-gunner is broken for months? or bugs are ignored? or things aren't like promised? etc, etc. Of course people have the right to complain or "bitch" in such matters, if they paid upfront.
And what would the "no complaining/bitching policy" exactly help with?
Did people forget F-16 release, (it's 1 year old now). SC no new features since release. Yak-52 no bug fixes for 3 years. AV8B half-baked systems +5 years, out of EA with ED's approval.
Not buying Mi-24 if it doesn't have the "more sophisticated AI-gunner then Jester" or Multi-Crew at release. No more money upfront until I see a finished working product.
