I don't know if this is the right place to post this, but I don't like that there aren't two different analyses for Choice Scarf and Choice Specs on Rotom-W. They actually play quite differently; Scarf functions as a revenge killer, while Specs is more of a nuke. Specs can also afford to run Modest because it doesn't have the ability to revenge things like DD Haxorus and DD Dragonite, and could use the extra power to break through things like Ferrothorn in the rain more easily. It doesn't need to run Hidden Power, since Specs Hydro Pump and Specs Thunderbolt are strong enough to kill most things anyway.
That one set should be divided into these:
[SET]
name: Choice Scarf
move 1: Volt Switch
move 2: Hidden Power Ice
move 3: Hydro Pump
move 4: Trick
item: Choice Scarf
ability: Levitate
nature: Timid
evs: 252 SpA / 4 SpD / 252 Spe
AC: Thunder over HP Ice or Trick (rain). Bulkier EV spread and Modest to let it eat Scalds and stuff better, and hit a little harder (fast enough for Jolteon, I guess).
[SET]
name: Choice Specs
move 1: Volt Switch
move 2: Thunderbolt / Hidden Power Fire
move 3: Hydro Pump
move 4: Trick
item: Choice Specs
ability: Levitate
nature: Modest / Timid
evs: 252 SpA / 4 SpD / 252 Spe
AC: Thunder over Thunderbolt (rain).
The world would be a better place if I still had SCMS access. >.>
