Who is SE developing content for in this game?

Thats a pretty weak argument, exclaiming running through the same content over and over with alts(jobs) is whats needed to fill out the void left by the devs?

Huh?
Is that not what it means to have lasting content?
Besides it's entirely dependant on what you consider "lasting" content in the first place, in the end it's all just about what you find the most fun.
I know people who spend their whole day doing HoH, people who do nothing but Eureka, players who barely even touch combat classes and would rather craft and gather, players who spend most of their time in PF practicing optimising their play in extreme primals and savage raids and just players who do a little bit of everything.
Clearly these people find this fun, running this content over and over again is something enjoyable to them, and as long as these people exist you can't say SE isn't thinking of its players.

If you don't like the idea of doing the same content again after you've done it once or branching out to try new types of content which you may have dismissed at first, you're welcome to unsubscribe and try out some different games while waiting for the next major patch release.

Thats the sixty four thousand dollar question, isnt it!
