Ask my Eeveelutions--the only moves that mess with stats on my team is my Vaporeon's Haze...
I have Jolteon with Thunder Wave, Umbreon with Confuse Ray and Toxic, Leafeon with Synthesis, Glaceon with Mirror Coat, and the rest is all raw attacking. Jolteon, Glaceon, Espeon, and Vaporeon are all beasts with Special Attack, and two of them are gifted with fantastic speed (the other two rely on massive HP or good defenses...)
But, yeah. I'm pretty much all-out offensive, maybe relying on a Confuse Ray/Toxic combo or Haze (Bronzong's Calm Mind was a pain in the butt without it), but otherwise I just don't really see the need...
However, I do intend to keep Sword's Dance on Leafeon ^^
