- People know they need to get help from others. There's less bad behavior.
- You can't cheese anything, like running in to a camp to grab the quest item, letting yourself get killed, and then resurrecting.
- You find it acceptable to do side quest things like making potions and other useful stuff.
- The levels below 60 are no longer a speedrun with barely anyone else to be seen. People die all the time, and they restart all the time, so the lower levels have a lot of life. On non-hardcore, getting to 60 is inevitable.
- You have to prepare properly. Not only bringing all the consumables you'll need for raiding, also knowing what the boss is gonna do.
- Because the game is old, you get older players with old people issues like having kids. It's much more sympathetic towards life getting in your way.
- You feel an actual adrenaline rush when things go wrong. You might have 8 days played on a character who could die if you don't get out of a sticky situation. People are constantly reporting heightened heart rates. If you play non-hardcore, it's just "meh I'll run back".
