Ok just curious as I am having conflicting and non existant answers to this from guildies.

What are good food/flasks/potions etc to take on a raid as feral tank?

A few of the best for each would be nice but the best possible is good enough as well. Just trying to farm/stock up in my down time so that come raid time I am good to go and not running around trying to gather stuff at the last min.

In my opinion, it depends on what you're lacking in. I gear towards Agi and Armor, while getting as much stam as possible. So, I rely on raid buffs to bring up my stamina, and a flask to hit the crit reduction cap. Thus, I use a flask and 20 or 30 stam food. However, when I get my last piece of T5 and reach the armor cap (almost there--will need some BT loot to make it), I'll start swapping some gems for stamina, and then I'll use an Agi Elixir and 30 Resilience Elixir.

Need Stam:
Flask of Fortification (500 Health, 10 Defense Rating, Flask)
Elixir of Major Fortitude (250 Health, 10 HP/5, Guardian)
Elixir of Mastery (15 All stats, Battle)
There's a -lot- of different Stam foods. You can either get a 30 Stam food (Fisherman's Feast, Spicy Crawdad) or 20 Stam food (Mok'Nathol Shortribs, Feltail Delight, Talbuk Steak, Clam bar, etc.)

Need Dodge:
Elixir of Major Agility (35 Agi, Battle)
Elixir of Mastery (15 All stats, Battle)
Warp Burger (20 Agi, Food)
Grilled Mudfish (20 Agi, Food)

Armor/Damage Reduction:
Elixir of Major Defense (550 Armor, Guardian)
Earthen Elixir (Reduces all damage by 20, Guardian) [I've only heard of it, and I don't know how many, if any, actually use it]

Reaching Crit Reduction Cap:
Flask of Fortification (500 Health, 10 Defense Rating, Flask)
Elixir of Ironskin (30 Resilience, Guardian)

Use whichever best works for you.

I usually go with the following:
Elixir of Major Agility
Elixir of Major Fortitude
20 or 30 stam food

I use on most of my runs
Elixir of Major Agility
Elixir of Ironskin

Elixar of major Defence simple +armor
Elixar of major agility simple +agi

cheapest and easist to go thru

Elixar of ironskin good ONLY when really needed to raise resilience at all cost
Earthen Elixar honestly i have used and its a waste of mats

Flasks = good but suck at the same time. because it locks out battle and guardian pots

decent flaks -
fortitude... uh.. thats it for a tank
relentless assualt - good for DPS

Dreamless sleep pots - great for resto/balance
