An aside about food:
In terms of grocery ingredients, 10-man feasts and +300 food are equal in materials/serving; a 25-man feast is 20% less expensive. Comparing Ironpaw tokens, however: a feast for a raid 'costs' 1/5th an Ironpaw token, but feeding everybody +300 food 'costs' either 2 tokens (10 man) or 5 tokens (25 man). Cost-benefit analysis suggests that, for most raiding guilds, on most bosses, feasts make more sense than +300 food, as they require a smaller investment.
Sub-1% wipes happen, regardless of whether or not everyone has the best food buff. A near-1% wipe means that your group almost has the encounter beat, and an additional +25 stat for everybody will almost never matter as much as improving execution. Under the premise that an increase of +25 stat corresponds to an increase of 100 dps from every raider, then 10*100 dps = 1000 dps, 25*100 dps = 2500 dps. Per minute, that's an increase of 60k damage or 150k damage. If the average boss fight is 7 minutes long, that's 420k damage or 1050k damage. Compared to Feng's health (presuming he's an average boss from this tier, being the only true single-target fight without a significant movement/mind control gimmick), that is at best 0.28% of his health. Improved execution is massively more likely to make a difference in downing a boss than the best food taking out even 1% of their health.
+300 food is indeed worth mentioning, and it merits consideration here in a comparison of racial abilities. BUT, in a comparison of racial abilities, it is critical to keep the big picture in mind: the dps gain from racials will be at most ~0.5% of a raider's output (and generally decreases as gear levels increase).
