Think about it. HP water is super effective and boosted by the rain, but yet it still does less damage then a resisted Megahorn. That's kind of useless, except on Heatran, but even it the rain, heatran's fire blast will still have 360 power after adding STAB, type matchup, and rain weakening it. I'm not going to do a calculation, but 360 power coming from 130 attack seems pretty bad.
And Charizard/Moltres? Sure, they both x4 resist Megahorn too, but how common are they in OU again? They're crippled by stealth rock anyway.
Oh, and most Volcarona would try to take advantage of it and use quiver dance, making HP water do even less damage.
Finally, if you are using it in the rain, why use HP water when you can just swap in a water type? Or are you actually using rain without one?
Edit: It looks like LoZ Skyward Sword is coming out in Sunday in North America...Kind of funny how the POTW will change to a warrior then.
