"what's the feeling" - I have no feelings..
I only have any issues with when you get down to the 40% whiskies - adding water technically makes it not whisky anymore (under proof).
But --- !! for sampling and critical tasting, it can have merit (drops of water that is). There are many esters in scotch (esters=yummy bits) - some of them are alcohol soluble (yay) and others are water soluble (meh), so adding a few drops of water can release those esters without changing the base characteristics of the whisky in hand (I have had plenty of scotch over 60% (120 proof)) , if water has been previously added (i.e. bottle strength releases - 43, 46, 50% abv) then those esters are already out of the bag (bag = cast strength whisky). So adding water does not gain those benefits, but in some cases it can make it more palatable. But there are may cases were adding any water makes things horrible (case of a 15yo Bowmore from OMC at 50% - any drop of water made it taste of ash, and the more water you added, the worse it got, solution=drink it straight from the bottle ).
