It's not arrogance. It's just a fact. If you don't like it, say why. Just don't whine about it.
Sure and it was. A good observer of the user interaction learns or is trained to turn general complaints into specific ones, without the user him or her self making them specific. This can be done by backing things out until the complaints go away or by changing this or that thing so as to see what effect on the complaint it has.
A master of excuses rather than fixes it is who burdens the user with requests for more specifics rather than to set out and determine those specifics himself.
To paraphrase Thomas Edison -- 99 "failures" to make one success.
