Only problem with "for fun", is that SE isn't doing anything to make progression after 2.2 different from current progression... I mean... We're getting a new tier of Tomestones which we'll presumably obtain in the same way (running the new dungeons, Coil) and used to obtain the same top tier gear, and then we have more Coil which, OK, that will be fun at first, but then it's right back to the same problem current Coil suffers from, and suffered from very quickly after launch at that.
I'm not against this progression model, I'm against them putting zero progression into it... Where is the progression when we're doing the same thing we were doing at launch?
