Since we appear to be going off the deep end again, please remember this thread is about a proposed "expose" system/ability. If you would like to discuss detection versus stealth in a more general sense please use one of the many dozens of theads that already exist on the topic.
As an aside, if wish to discuss the above please do your research on the relevant mechanics, abilities and spells, and available in game items. If you don't know, ask. Try to make fair comparisons, i.e spot vs. hide and listen vs. ms, and don't fall into the traps of argumentative fallacies. Not only will you speak with a greater deal of authority and suffer less nitpicking over minutiae, you might learn something new!
