wow, you just do not want to admit you are wrong. that is EXACTLY us saying "we like this" and "dont do that". HoW is almost entirely player acknowledgement: Keys too rare? up the odds and guaranteed drop instances. want to keep your old shit relevant (and even end-game)? Etheric Light. Cozmo confirmed that they know. hell, im pretty sure they already knew "leaving behind" some exotics would not be very well received, they've acknowledged players great affinity to our exotics all of the time. Vex Mythoclast was originally stated to be "locked in time", but look, it got brought up to snuff didnt it? they'll do the same agian.
