Potions are essential at least in PVP, and very helpful while leveling. Our FC saves Tab 1 just for pots, food, and low level HQ gear. So nice to have a raid group with HQ mega potions for burst dps during phases, or when Im tanking and give the healer breathing room with a HQ Mega VIt pot. HQ x-ethers are equivalent to and extra Convert for Blk mages, making trash pulls that much faster to burn. Spine Drops, Smelling Salts, Slow Ward Pots and X-Elixirs are almost mandatory for a good pvp experience.
