Consumables are yet to be properly explored, and to see what stacks with what. If we are to assume anything from Vanilla or Season of Discovery, we can expect a lot of different consumables that can help you in raid content, some a lot more than others. Stat Priority is a good way to see what consumables should be preferred.
Example of fully optimized consumables for Feral Druid DPS
Thistle Tea,
Flask of Natural Precision,
Elixir of Ferocity,
Elixir of Cunning,
Elixir of the Owl,
Elixir of Sages,
Elixir of the Phalanx,
Greater Mageblood Elixir,
Winterfall Firewater,
Swiftstrike Steak,
Dragonbreath Chili (use after food buff),
Rumsey Rum Black Label,
EZ-Thro Thorium Grenade,
Goblin Sapper Charge,
Elemental Sharpening Stone,
Ground Scorpok Assay, and why not add
Noggenfogger Elixir for the looks.
Although this is a fully optimized example, the most important thing is to make sure you have something that covers Strength, Agility, melee attack power, and at least one elixir with 2% increased critical strike chance since it only counts once anyway. On top of this, a Flask is always recommended, along with a Food Buff and a sharpening/weight stone.
Camping
In Forever
Basic Campfire Kit is introduced allowing you and anyone else around you to get 3 powerful buffs depending on what professions people around them have. It is very good to optimize your camping buffs if you're with a group for leveling or even endgame dungeons. Later on, you also get access to
Journeyman Campfire Kit and
Expert Campfire Kit which allows for more profession items to be placed by the campfire. As a Feral Druid, you will prefer
Camp Chair (until you get
Leader of the Pack),
Fish Bowl,
Camp Tent,
Sharpening Wheel and
Lodestone.
Food Buff
Spiced Wolf Meat and a lot of other food buffs in all level ranges now have "Additionally, experience gained from kills is increased by 5%". It takes 10 seconds to get the buff, but that 5% experience increase from kills is worth the time spent.
Flank au Poivre or
Swiftstrike Steak are likely to be the best food buff available at level 60.
