I don't think that's true at all.
I haven't seen the Harper match from last night yet, just the aftermath, but he's had a slew of fun TV matches so far. Styles, Rusev, the Gauntlet (Big E/Samoa Joe), Benjamin.
If you look at the WWE over the last ten years or so, the TV matches have always been the real strength. You have ECW and/or a bunch of other C-show stuff in 2008-2009, the shield six-mans in 2013, maybe Cena's open challenges depending on how you feel about those.
How many feuds does WWE actually nail?
