Yeah, this just proves you don't really have any understanding but let me explain so you can understand.
if we are looking at golems, then Ele has always had strong benchmarks, this is true, however, if we are talking about actual end game content like Raids or Fractals, then other classes can do similar damage with less effort, this makes Ele less viable, Pistol doesn't change that at all. least to say that they haven't really gone all out on Pistol either, there is zero imagination, zero creativity and zero thought into it.
I forgot to add that other classes have access to more boons or CC as well without losing any dps
