I agree that Genie+ does not work. In fact, I don't believe Disney was being altruistic all those years in not charging for FP+. I think they knew full well that - in the unique circumstances of WDW - any skip the line system would have severe limitations and people are more likely to accept a free one on the theory that "you get what you pay for."
FP+ didn't work for everyone, but it worked very well for a great many people who were amenable to doing more than going from attraction to attraction. There's so much to see and do at the WDW theme parks, water parks, resorts and DS. A few rides at scheduled times allowed us to enjoy everything at WDW, including resort entertainment, boat rides, dining, shopping, water parks, parades, fireworks, etc. I know that FP+ didn't work well for those who were more centered on doing rides and didn't like to plan in advance, so I was willing to see what Disney would come up with that would satisfy them. With Genie+, the answer is "nothing."
I wish I had an answer to how Genie+ can be fixed. My family has decided to fix the issue by booking our first cruise on Royal Caribbean next year instead of taking our previously planned vacation to WDW. But I'm an optimist with a pretty good number of DVC points, so I'm following along and keeping an open mind as to whether Disney can come up with a system I can work with - something I've been able to do until the fiasco known as Genie+.
