I believe I made myself perfectly clear why some specs were not listed. Those that play Arms in raids probably do so because they like it, or because it's their PvP spec and they can't be arsed to make an offspec and learn to play it. Either way, they're not putting an effort to swap a spec and reforge their gear accordingly, which already shows that their parses should not be taken seriously.
I think the differences in 10H and 25H boil down to 25H being more prone to huge AOE fests, like Feng, where WW performs greatly. Even then, this was not really my point. Maybe I should have left raidbots link out altogether. The point was that if we make this forum an echo chamber where everyone praises how glorious the spec is in every aspect, it has huge impact to WW community, which is why I also pointed at MMO-C Shaman community. Look at Warlocks or Rogues, who currently parse highest for ranged and melee respectively. Is their forum full of members praising Blizzard for their great design decisions?
Numbers wise, we can't say anything about 5.2 yet. But concept wise, we're getting some direly needed love.
