I for one think that everything should should upgrade when you use it, with most things building off of some simple actions. For example, with all items you could look at it to get a quick description, or examine to get all the details that your charactor can know. This however would take a whole minute of sitting there, doing nothing else, and everyone could tell you are doing it. Then, this would be expanded to players, so that you could look at some one to find out what there race is, and maybe which is there highest skill(without giving a value). Then, examining a player would give you alot more info, but they would be alerted that you are trying to examine them, and all they have to do is walk away before the minute is up, and you find out nothing. Or something like that.
