Humans are "meh" due to Versatility, which leaves NEs, Gnomes, and Worgen. Worgen = Crit, which is decent for Sub and Combat, but is neither's 1st or 2nd favorite secondaries. Gnomes = Haste, which is great for Combat but horrible for Sub. NEs = Haste or Crit, depending on the time you're raiding + Shadowmeld, which I feel is the strongest combo.
The reason I feel NE is the best is because even if you raid at night and get Haste, while this doesn't really help Sub out, it benefits your Combat spec a lot while still giving you Shadowmeld, allowing for a free Ambush for Sub. This gets you another Ambush in during a FW and extends your FW out another 10s, helping a lot more than you think.
So, in my opinion, and from what I've seen myself, it goes NE > Gnome > Worgen.
