Per the 7.2 patch notes, the best Legion feast (Lavish Suramar Feast) grants 500 main stat (up from 200) in 7.2. This means that for most classes, feasts will be better than all other food options. Even the lesser feast (Hearty Feast) will grant 400 main stat.
If you cook your own food and don’t have rank 3 of the feasts, you might want to head back to Nomi with some materials.
Make sure your raid group is ready to feast on some feasts!
