I agree, the time skip was the point where things started falling apart. Having the Excalibur and Trident was close, the difficulties of juggling two crews of characters, but he seemed to be figuring it out, and then he jumps forward a few years, adds Bravo Station and Robin, Si Cwan, and Kalinda on New Thallon, and it was just too many balls in the air for the story to be juggled properly.
That said, I've still enjoyed the series from After The Fall on. But while I want the cliffhanger from Blind Man's Bluff resolved, I'd also be content with that serving as the finale for the New Frontier line, at least for the time being (I've never liked being left hanging, so ending it at BMB doesn't work well for me). It feels like the magic is gone, for lack of a better way of putting it.
