The only thing the applet does is making sure that you don't literally waste EVs (as in, if there exists a spread that gains extra stat points with no loss whatsoever) I'd probably see if there's a specific physical attack you don't want to be OHKOed or 2HKOed by, and dump the rest to special defense. Something like +2 Samurott Megahorn, or Scarf Emboar Superpower, or something, as long as it doesn't require too much investment. Or, you could select a specific special attack, like Samurott Ice Beam, and put the rest in physical defense.
And to be fair, Dragonair's specially defensive typing matters a bit less now that Magmortar was banned, but of the physical attackers that Geoboy mentioned above, things like Carracosta and Sawsbuck have a stronger (and more easily spammable) moves that hit it neutrally.
