Yeah but that's a cheap design ploy to make it more appealing to a greater audience, if everyone knew you would have to go 1/200 very few casuals would bother, it's all about abusing psychology. The fact you can go 1/3 is what encourages those kinds of players to do so, even if it's just 1/3 on one body and 1/200 on the next, it still puts that hook in you that it "can" drop really quickly, or on that next kill (even if it happens to someone else, it still puts it in your mind). It's about getting you addicted, skinner box etc.
I hate that I work really hard and someone else breezes one but i know why they did it and I know why they are so reluctant to change it. Sadly these bodies never were status or reward items, they were just lucky dips that anyone could get lucky and get and should be seen as such. If you worked your ass off going 1/400 and are proud of it the guy next to you with the same body and all aurore in every other slot that did VW twice wants a word with you, this isn't endgame really it's just an nm fight where half the alliance can be carried with a pure lottery game at the end. If they put a point system in next update where you had to kill a set number of each NM and have all the clears to +1 the bodies it would at least even out that the good players would feel more rewarded, VW desperatly needs "I'm good at this event and here's my loot to prove it" and not "I did vw and got lucky".
They didn't make a design mistake in their mind, they planned it all to work the way it does and for reasons. That's why they won't change it, they know why we hate it but the reasons we hate it are the reasons they like it.
