I'm certainly not going to miss the Sub/Protect strategy, and honestly, who would? I feel as if one of the only true counters to the Toxic Spikes + Stallrein combo is Magic Guard users, as they can defeat Walrein without having to sacrifice anything. Furthermore, the Toxic Spikes will shield pokemon like Clefable from extremely aggravating Blizzard freezes. But even if I use a team that is loaded with hail immunity, Walrein is still annoying to face and will make a match 60+ turns long if the opponent is persistent enough to repeatedly subtect. It's stupid. Whether its out of spite and/or my belief that Ice Body mons are indeed broken, I'm leaning heavily in favor of a Snow Warning + Icy Body ban. It does not create stupid limitations in NU (by banning Ice Body universally), it preserves the non-broken aspects of hail in RU, and Hail stall and offense are still totally viable. Hail stall does not require Ice Body.
