WSBK? I've always found WSBK to be more entertaining than MotoGP, which, in recent years, is more often a borefest than a good race. Stuff like Catalunya this year is a rarity. An example would be to compare the MotoGP and WSBK races at Brno. WSBK was entertaining, MotoGP was bloody dreadful. And it'll only get worse with the cost-cutting measures next year.
I agree the cost cutting measures will make Moto GP worse, just like it happened in F1.
But WS also had shitty races at Miller and such.
Single file racing is single file racing, no matter what type of racing machine you throw at it.

As for Valencia, I'm more inclined to believe the engine formula is to blame for F1's struggles with overtaking. Look at a race like Hungary 1989 and you saw many overtakes, despite Hungary being a shitty circuit. Why? The engines were all very different in terms of configuration and power output. Unfortunately until something is done about the current F1 regs, we won't see that much more overtaking, regardless of the circuit.
Engines weren't the only thing different. Chassis where also more different and some teams had carbon-carbon brakes while other didn't.
So you had straight line differences, brake distance differences and cornering speed differences.
Close spec/semi-spec cars are horrible for road course and street circuits, hence stuff like push to pass, optional tires and the front wing.
As ChampCar showed P2P needs ~100 hp or so to be effective on most/many circuits, and IMO you'd also need a push-to-outbrake system, and I'd even say an active slipstream-ing system.
