I play in the top lane. I actually don't expect my jungler to gank and I perfectly fine with that. I think that unless the kill is "free" for the jungler he doesn't need to come top and can focus on the carry lanes.
I play
and typically just wait for the outscale and manage the wave.
I don't really need them to come top unless the wave is froze on the other side, in which case I am probably very behind and died a few times, Doesn't happen too often but as long as my CS is even with the opposing top laner I don't really require a gank.
I also think lower Elo emphasize and request ganks because they don't know how to lane! Once they are behind they don't know how to farm under turret or avoid dying, hence the incessant gank requests.
