It sounds very much like your just burning through the new content after every patch and then join the group that cries "the end is near" as population drops before the next big patch. This cycle has been around for nearly a decade now across all MMO's. It not like any of this is new or even different in any way.
Every patch simply further progresses the game, the rate at which content is released will most likely not improve going forward so try not to get your hopes up if that's what you are looking for.
my nemesis,,the content locust
new missions doesnt save a game,,the way theyre presented does that
most players will do the most braindead missions, if theyre made in a entertaining way
ive collected pretty much anything in mmos,,,from bears butts, to plasma samples,,thats what a mmo players does
i wouldnt do that, if i didnt have fun , while doing it,,ot get a good reward for it at the end
