Ideally, people will be responsible for their own flasks or guardian/battle elixirs.
Casters and healers should have weapon oils. This doesn't apply to melee, because it doesn't stack with Windfury Totem, iirc.
Healers should have farmed up some Dark or Demonic Runes.
Anyone who needs to reach a health check on any specific boss needs to make sure they have some Rumsey Rum Black Label (can buy off the vendor in Southshore within the Old Hillsbrad Foothills dungeon).
Scrolls to cover any important buffs they may be missing.
Priests should bring Sacred Candles. Paladins, Druids, etc. bring their counterpart buff reagents.
Haste and/or Restoration drums.
