Not all skiers have versatile skills and I don't really think that should be a reason to shit on anyone - for instance, everyone respects Wabs too and he has only ever done like 1 backflip (it was on his Instagram) but he is dirty at rails as well. If skiing to Cory means sliding rails and to me it means dropping cliffs, then that's fine for both of us.
However, I think a lot of us are disappointed, myself included, because we expect SLVSH to reward riders with a versatile skillset instead of people who are incredibly good at one unique thing and take advantage of their opponent by doing 4 front swaps on a down rail. Not to mention, a lot of the enjoyment of watching SLVSH comes from seeing riders who are way better than we are trying shit they have never even thought of trying. It's great watching riders progress in a pretty raw format that doesn't always result in them landing the trick cleanly, but we get a lot more respect for them either way.
