You know how shitty of an argument that is? "Durr hurr, all mmos do it, dumb head!" Destiny isn't an MMO. And even if it were, real mmos give you an appropriate amount of content to deal with losing the previous stuff. Destiny just says, "Whelp, lets just make everything outside of PVP useless. Oh, don't worry. You silly little PVE'ers still get some strikes, and a really long strike".
