Vaporeon is used a more than Venusaur. More than lots of stuff. It's one of the 4 standard bulky waters, along with Suicune, Milotic, and Swampert. Wish, BP, and Haze make it stand out among the 4, though it's still the least used... Don't knock vap! lol. Srry, vap fan here. (see: avatar)
Oh, if Suicune ever rises any more in popularity, Vaporeon numbers will grow with that, as it IS the best wallish thing for it. Haze + water absorb.
I also use dragonite for heal belling, but yeah I'll agree it should maybe be borderline because everyone's stupid with Salamences. There's like 5 ppl that have ever used dragonite for an extended period of time.
Venusaur should stay in BL because I haven't seen many. Never EVER seen one on a tournament-caliber team...
Vap: Stays OU.
Drag: BL?
Venusaur: Stays BL.
Do make it clear that BLs should stay out of UU fights unless a warning is given, it really sucks when you play a rated UU match and a freakin Dodrio/Miltank/Jumpluff comes out... BL = TOO STRONG FOR UU
...and Walrein users should be required to put "I USE WALREIN" in their profile for UU teams. That is, if it doesn't go to BL.
(Meh, I'd just like to say that I'm not a horrible UU player, I win 90%+ of my matches (okay, okay, most UU players just play it for fun, but whatever), but a certain guy with Walrein beat me three times. And I have to say that it was the Walrein that did it, not the other pokes. Try playing UU with a team that you didn't specifically put Walrein counters in, and you'll see something.)
Think of Walrein in UU as Blissey in OU, annoyingly hard to kill, usually takes forever, but dang, we don't get stuff like tyraniboah or McIceGar in UU...
On another note that's not Walrein hating...
Donphan: BL? Effectively extinct methinks, since everyone that needs a ground uses... um... well... rhydon's apparently considered cooler, and swampert's more used.
