Regarding the Sniper zoom...I think that MOH:Heroes handled Sniper zoom the best with just a turn of the wrist...doesn't throw your aim off at all. REALLY if you have a creative development team, button placement, or LACK THERE OF won't be an issue.
The Interweb is about overreaction, this is what makes it great!
...Imagine how boring the interweb would be if everyone thought logically?
