That would be cool if there was a hunger/dehydration factor to hardcore. We already have food and drink, and I can see higher-level/player-made food lasting longer than the food you can buy from NPCs.
Hardcore should have a hunger and thirst meter and uncooked food should give you diseases. Get fishing. Mage food heals you but doesn’t satiate you like that sweet home cooked grub.
When you are losing the battle and need to run away, you disengage the baddies by running past a lower level player. They are coded to decide to turn on that player instead because they know it will be easier to kill something weaker.
EverQuest has it to where if you run out of food/water, it starts saying that you are hungry and thirsty. It affected regeneration of health and mana. FYI, the food and drink would automatically be used out of your inventory.
I did like dropping things on the ground.
My guild used to play a game with a trail of little bags on the ground. Or leave things in the newbie zone for a random to find. I would charm low level creatures, give them weapons and … some times the chat would light up with an excited person talking excitedly about the magic weapon they found on a gnoll.
During the Luclin expansion, there was this false bridge inside some giant cave…you tried to cross it, you died from falling…but there was an invisible bridge crossing the same chasm. I played a Mage and would drop conjured items on the invisible bridge so we could cross it. It was also fun equipping guards with conjured gear.
Also, if you killed a mob that was weilding a weapon, you know you will be looting that weapon once you killed it. I used to equip low level mobs with conjured weapons all the time.
-Getting attack from behind while staggered does % health damage.
-To emphasize your cowardice in your final moments you expell your bowels as a final defense if killed when running away. When your flesh withers away, players can find smelly piles of clothes. Very rarely, some of the clothes will also be soiled by Player Tears: these clothes can be burned in effigy to incite a dance party 400 yards in any direction. Even on the opposite faction and their leaders in the capital.
