Dude, the ladder is known for having players oblivious to this forum even if they happened to be good. That also has nothing to do with the discussion on how good Vaporeon performs as a whole. All this talk about rank one attains with a pokemon does not influence its rank: did you know I managed to breach top 7 with a Riolu team in NU? The reason for that is not because Riolu is fantastically broken, but because most players I faced were inexperienced or unprepared. Similiarly, Vaporeon likely saw success because players didn't have the means or knowledge to take it on, not because it functions exceptionally well. Vaporeon itself offers synergy issues when trying to utilise Hydration, since it already clashes weaknesses to Politoed, whereas other Rain abusers in Tornadus-I, Jolteon or Thundurus-T can at least cover a weakness or two, while Vaporeon adds almost nothing in terms of defensive synergy. Hydration Vaporeon does a good job at sitting there and take hits, but I often ask myself if there is a better way to use the Rain while not being completely helpless against most of what opposing Rain has to offer in Ferrothorn, Taunt Jellicent and Thunder abusers, and not be completely neutered against other weather. Other bulky Waters can still do their thing while usually not giving a damn about the weather change (it's more the boost opponents get that they are worried about), but Vaporeon loses its reliable recovery, which is a serious issue as that is the biggest thing Vaporeon has going for it. Vaporeon also doesn't have the useful resistances other bulky Waters have. Rotom-Wash has a Flying resist and Ground immunity; Jellicent and Tentacruel takes Bug and Fighting attacks; Gastrodon has an immunity to Electric. These factors are enough to make one reconsider Vaporeon's placement on a team, as it is generally more important to have resistances than to simply have a sponge that may or may not survive 2HKOes from these threats. While Vaporeon has very powerful recovery, it also generally takes more overall damage from threats due to its lack of important resists, which can force it to recover more and support / attack less. This lack of resists are compounded by the fact that hazards can inch Vaporeon into 2HKO range from most offensive threats. Wish, Roar, and Heal Bell are notable advantages, but obviously cannot fit all of them into a single set and faces competition with Chansey anyway. Water Absorb Vaporeon has very inconsistent recovery, and its low speed makes it difficult to heal and support at the same time with Wish.
