Well, experienced archers know very well when to retreat in order to not get bumped/interrupted. If this bumpradius ( Yes, you do have to hold lmb in order to get the bump, otherwise the shot will just be canceled, which however is pretty much a freekill also ) will get enlarged, archers will simply start to run away even sooner and wont let you come that close, if running away is their intention at all.
I cant really say I care about this because I dont usually get kills from that close range but in the end its one of those suggestions that made archers the kiting class we see now in the first place. Its just another change that works in favour of melees, allowing the average melee player to get freekills without even knowing what he is doing and its furthermore again forcing archers to keep their distance and to run away, which they can if they want to.
The problem, as mentioned a lot of times before is the ability to kite itself. As long as archers can kite and you give them more reasons to do so, they will. Give them more melee capabilities but increase the speed penalty when drawing a bow Id say. ( Yes, contrary to popular believe its already implemented )
