Aaaaaaaaaaand sims, I see your point, but luck isn't useful in the hands of something useless already, like Dunsparce. It's still going to get crushed by everything. Things like Garchomp and Skymin are good enough that many believe the extra luck they have tips the scale, and that's what I'm interested in.
Still, if you're trying to ban something, you have to prove that it's uber or BL or whatever. In the Garchomp discussions, the whole "overkill" thing was used, but I just didn't see it and still don't. I have a feeling that Skymin could have a very similar fate when it comes to what people actually decide to base their votes on (assuming Smogon keeps that system in place, and as much as I don't like it, it's better than most anything else).
I think my mini debate with Vance kind of shows it...people interpret luck differently in many cases, and I don't think any well thought-out interpretations are really "wrong," but it does show how weird the issue is, hahaha
I still think people whine about luck way too much in a luck-based game to begin with, lol
