that isn't really post-launch content tho is it. As it was promised as a stretch goal of the kickstarter. It's okay to say it's not sustainable, but you are admitting that you do not wish to develop past what was initially planned which is absurd for an mmo and essentially puts an expiry date on the game the moment it's released.
I'd argue it's content coming after launch, even if it was a stretch goal. The amount of unplanned, unexpected content we've included in the game during these past years should make up for it. We have also explained what our take on the MMO format is, and what to expect and not to expect.
