Av is a 40 man raid. Do you go on your 40 man guild raids expecting everyone else to bring consumables for YOU? Their are a few different ways to get 55 food and water. One merchant sells a consumable that does food/water together even. You mention you prepare before going to a bg even. Why cant others? I come prepared to the point that i only have 6 slots open in my bags. Why? Because I have health pots, mana pots, faps, speed potions, shadow/frost shield potion buffs, magic resists potions, and more!!! Plus my pvp/pve gear. So I couldn’t even fill up my inventory to get a mass of mana potions because I am coming to the bg ready to fight. People. Need. To. Be. PREPARED.
Edit: And those six slots are filled with my food/water.
