because we, as the gamers should NOT like this , because if you dont speak up against this tactics (and yes they are actual the holy grail of economics , i work in this: see also Kaizen, 5S, SixSigma, 7 Muda,.. etc..) then we, as the gamers will become the milking cow and EVERY studio will try to do the same and sell you a Complete Game for 300$ by chopping into tiny pieces and spoonfeeding it to you... best proof you can get now is the "weird and unique "beginning" of the "undying mind "Strike" which is in fact the Mission that continues after the Black garden which was NOT the final "bossfight" just due to lacking a boss. the "strike" starts with a beaten Black garden with "dead" Vex laying around.. the only time you see vex laying dead is during the cutscene at the venus academy where you meet the exo stranger for the first time.. also in this "stike" one the vault of glass vex are introduced for the first time.. and on top: last year there was an AMA from aguy called Architec404, who claimed to have been a tester for destiny and he described exact this scenario: the black garden wasnt the "final" mission in the original storyline and continued right on.. which is currently happen with the undying mind strike, so unless this guy was utterl lucky with guessing or a clearvoyant, he probably WAS the tester for destiny he was claming.. since this scenario has come true.. THATS the reason why .. THATS the reason why YOU should care..
