Make a friend and run it with them? I'm having a pleasant time of it.
The only thing I want from the IA is a save function. Anything else they might add is a secondary consideration.
After that, revamp the rewards. The IA rewards do not match the time spent, even in Arc 1. That could include new sets, but I'd prefer they up the lead drops, the number of fortunes, etc. Give us goodies. If you want us to spend time in there, reward us and for heaven's sake, let us save.
