The way I would like trousers to fit is basically how you explained it in your first post. A nice line at the front and back, with a slight break at the bottom, and not to have any pulls/creases when standing. Of course it has to be comfortable without excessive restriction on movement or when sitting. The other faults that you have outlined I have not really paid attention to. Usually when I have a fitting, I wear the coat and trousers around the sartoria for awhile to gauge comfort before the tailor/pantmaker checks it again for any issues that I may not have seen.
When I've worked with one man tailors (those who make the coat and trousers themselves) or a tailoring house it can take up to 2 trousers to get the fit as I want them to look. Usually tweaks are made after I've worn the first pair and I've noticed some things I would like to change. Afterwards one fitting is sufficient to get my fit correct. With dedicated trousermakers, usually they get the fit I would like by the first trousers, and smaller tweaks to subsequent orders. This process is sometimes repeated when I choose a different style and fit of trousers.
Here are some photos that I've posted here showing trousers. The shadow chalkstripe was basically finished except for shortening.
