I would like to see Hurricane put to a vote. I've already argued for Hurricane quite a bit, but I think this post is pretty comprehensive, for my argument at least. I think it at least dispels the idea that it serves no purpose other than needless coverage; the differences really come in with whether or not we should be able to counter or check any non-Grass Fighting-types. I think being able to threaten Fighting-types realistically is as applicable to the concept (due to Poison typing) as being able to threaten Steel-types in their home turf is (due to our Fire-typing). Dry Skin was necessary to take advantage of the latter ability, because if we were destroyed by Water-types in the rain, all we'd ever accomplish is to threaten out Steel-types and then get owned by Tentracruel, Politoed, Rotom, Etc. In the same way, trying to deal with Fighting-types will get us owned by Stone Edge unless we have a move that really threatens them.
