Let's say they added an extra piece of combat content.

Everyone burns through it in a day and then continues to complain there is no combat content.

It is not a problem that SE can actually solve by making more content.

We also did just get some combat content. A deep dungeon. Personally, I'm still casually building up my aetherpool to do the higher floors, but I'm willing to bet some people burned through it in a day and are now complaining there is no combat content.
