I care because I'm really into the lore of the game. Despite what Bungie have done with it, Joe Staten and his team's original creation is a magnificent piece of sci fi. As a result, I get irked when pve players ask bungie to piss all over the lore in order to make the game easier for them. And your example might not be the best. I'm an old fart but I still solo'd izanagi's burden (aside from the bits you have to matchmake for). If an old fart can solo shatteted throne and brakion, it's a long way short of "mostly impossible" surely?
