Why do you have surf on Vaporeon? Same question with speed effort values. I was looking at the team last night and it seems like a waste of a slot you can use for something like Charm, Wish, Yawn, something. Vappy's role is to set-up and pass the ball, not attack. After 49 (when the real battles begin) you'll face 4 sets with taunt. So if it's there to protect itself against taunt users, you've honestly got nothing to worrying about with a Salamence on the team. (Miltank can take care of Aero)
Speaking of Salamence, Fire Blast will miss, a lot. Does that sound like a reliable cleaner? Get your Flamethrower on so you actually hit the opponent. Personally I'd want more attack values but with a weakened fire attack, you might need it. I'd check some calcs if I were you.
With Miltank, I'm not so sure it'll work in the frontier, but it's worth a shot. I just don't like the idea of a slow (half of its set cuts speed) sweeping pokemon without any sort of substitute protection. Critical hits look like your top enemy with that cow.
I'm not a big fan of the team, because baton pass hasn't seemed like a proven winner. But I don't want to dislike it because it might be an interesting project to see what happens. (experiments are the best remedy to fixing teams) I'd suggest looking into the frontier opponent sets and more research to see how you can better the team.
Don't want Outrage? Please elaborate why you're backing off on a move that, at +6, OHKOs some Skarmory. Dragon Claw is pretty much ridiculous at this point, if you're afraid of Outrage backfire, you're team isn't versatile enough to pick up the slack. (I overcame that fear thanks to Jump) Gee, it'd be better to give it a lum berry and something else the valuable sash.
Also, Vaporeon, Calm can work just fine. Heck, if I was using it, it'd be calm and maxed special defense. Acid Armor and or Charm (I'd use charm, but that's a BP team) picks up most of the slack.
