Well if you want it to shut down, no worries since they are ending all content development this year, lol.
I do agree it can be difficult to find people for content. The devs have been doing their best to improve that, but there is still a lot I find I can't do because the rewards aren't good enough to entice people, or the people who are geared enough to do the content have the rewards so they don't want to do it anymore.
My advice is to focus on things that are achievable - and do try to make your own groups where you can.
Also this is the wrong forum, this is for suggestions on the website... not suggestions for the game.
