You realize it's not just about buffs, it's about balance. Things are a lot more equal now than they were.
Draenei needed a buff; with hit gone. Assumption is that it will be equivilant to panda bonus.
Night elf had no dps racial at all. Now they have 1%, the most flavorful but likely weakest one, due to how it changes.
Orcs blood rage was already almost as good as Worgen crit, better pre-Thoks. Yeah they lost weapon expertise bonus but did they really need 3 dps bonuses? Remember they retain command pet.
Humans by contrast had only the expertise and lost that in favor of 2 half a % buffs. Something that will be weak to all but the most awkward of specs that constantly shift top secondaries.
Blood elves get the same crit as Worgen plus a resource regenerator. That's better than a speed boost, so I'd say BElf > Worgen most of the time.
Now personally I think it would be much easier to simply give every race one small dps boost, say ~1% to a different secondary/each. And one utility/fun activated ability; dark flight , shadowmeld, resource return, move speed, stam, stone form all fit.
Most races follow that, and spice it up further with some extra stuff. It wil never be omportSnt equal, but it's pretty close. Better than live.
