If use of Abomasnow makes other Pokemon broken, who would be more ban worthy, the Pokemon broken because of Abomasnow, or Abomasnow for making them broken. Auto-hail is lethal in nUU because it is the hardest weather to work around. With Rain and Sun there are large benefits in power, but they are going to end in a few turns, so they are more than managable. If you go with auto-Sandstorm, you are essentially playing with a team of 5, since after setting up the storm Hippoppotas is dead weight, and if the other team uses weather after he's down you lose your advanatage. Abomasnow not only gives auto-weather, which it shares with only it's pre-evo and Hippoppotas in this environment, it's also a totally viable Pokemon, so you're not gimping yourself to set up a weather condition.Should we deem this combination "broken" (I am yet to be convinced) then it is Walrein who should be banned. No other Pokemon are potentially broken under Hail. If we ban Abomasnow, Walrein will see little use unless your opponant wants to use Snover, if we ban Walrein, Abomasnow may still see use in UU, which would be nice.
In regards to it's support, it's not just Walrein, although Walrein is arguably the best recipient of Hail support available. Glaceon gains, along with Snow Cloak, 100% accuracy Blizzard. Very little likes taking hits like this. If one is willing to sacrifice speed for power, Specs will devastate almost anything that switches in. And there is no penalty for them using this strategy. Unless you have a very bulky Ice resist, it's going to hit, and it's going to hurt.
Any Snow Cloak user can work to abuse it and become a major annoyance. While many would not like to rely on it, Support Froslass is an example of what can be done with it. With that evasion, support like Thunder Wave and Confuse Ray, and Spikes, or even Substitute or Brightpowder, Froslass becomes a major hinderance to a team. It can lay down Spikes, status support, and stack Hail damage with an extra safety cushion. I'm not claiming this is fail-safe, and it's not the best option. It's quite risky. It is, however, potentially very effective.
I think that Abomasnow is very much worth a look. As a singular Pokemon, it is not a large threat. However, it provides incredibly effective team support that requires it to simply appear in the battle to potentially last the whole match. It's a support option nothing else can equate to. And as such it is worth a consideration.
A Pokémon is uber if, in common battle conditions, it can consistently set up a situation in which it makes it substantially easier for other pokemon to sweep.
First off, weather moves such as Sandstorm and Hail are definately not viable. My reasoning for this is simply that you can get a maximum of eight turns out of them (I believe it is seven if you include the turn you set it up, but I cannot be sure of this, can anyone confirm?) While this may be a viable strategy for offenive based weather teams (Sun and Rain, and it is "just about" long enough for them), it really does not cut it for Stall based weather teams such as Hail and Sandstorm. Imagine StallRein, it needs to break it's Sub Protect cycle 6 times (because I doubt it wouldn't carry Leftovers) to keep itself going.
Hail and Sandstorm are not viable options because of the benefits they provide. Rain and Sun are offensive in nature. They make attacks more powerful, increase speed, etc. They give an instant payoff. Such is not the case with Hail and Sandstorm. They are more support oriented in their use, with Evasion, Ice Body, Special Defense boost, etc. They are benefits meant to take effect over time. Many Pokemon that benefit from the effect do not benefit from setting it up themselves. That's why Sandstream is so good in OU, yet Sandstorm is not considered an option in UU, and why auto-Hail is so good.
