As a fan of the Thief Series, I like stealth play. It would be great if they improved how the AI deals with stealth etc.
That being said most of the complaints are choices. You have to choose to see stealth cones. You have to choose to re-stealth after an action.
I choose not to abuse stealth, use barrelmancy, dip, shove, etc. because *I* don't find those mechanics fun. However there are others who find those mechanics fun. Why would I want to impose my definition of fun on everyone by removing the things I don't like?
