iOS 8 problems? Leave feedback to Apple

(This is a user to user advice, as I got TOU violation for polling, I'll try to keep calm now and just make a suggestion)

Dear users: If you're having trouble after updating to iOS 8 like I do (and many others, as we can see in the forum), I think the best way to contact Apple is to leave "feedback". This way you get straight to them. I did, asking if we may go back to 7, not for any reasons but performance. My iPad mini 1st gen works terribly slow now. I did everything, restored everything to factory, installed it again. Facts: iOS 7 was 1.1 GB, 8 is 1.7 GB, there must be a difference there.

Remember how to: https://www.apple.com/feedback/

Thanks, and again I'm not polling here, just suggesting.
