I think that this attitude a great example of the arrogance that permeates a lot of the redesigns that get dropped on people today. Yes one needs to sometimes throw out suggestions (because they aren't aware of techniques) but when users complain or praise something that needs to be listened to because they are literally telling you their workflow and describing potential optimizations. Nothing is more obnoxious than designers telling me I won't want something! It's like, 'fuck you, you don't know me, stop discounting what sounds like a good idea!'

Ask things to your users, and then listen to them! Watch them when they show you things, watch them when they work, watch their emotions to see what they like and don't.
