Actually retyping something....
Essentially my personal issue and it may only be because I'm playing an exalted character that doesn't go off to kill goblins just because they have a tribe in the woods. She normally has no reason to explore and no map or known knowledge of the world around her, there's no motivation to go out and explore. The only source she has is fellow Order members (which is two right now) to even bother trying to find places to explore and train.
I don't see the big issue honestly. A higher level PC can always run a lower PC through an exploration area and get tons of XP
anyways - it happened once with the Asylum where all Teuivae did was stand around and get way more XP than any quest I've done. So opening a quest area wouldn't matter for the lower PC. If you're concerned about higher PCs getting XP from quests, just make a cut off for XP then?
Exmaple:
Kalianda - Hadrian Southbank -Warehouse - lvl 4-10 - Party Req 2-6
Let's say we turned it into: Kalianda - Hadrian Southbank -Warehouse - lvl 4+ - Party Req 2-6
Well, let's say a level 15 PC takes a level 5 PC. Well, the reward for the level 5 PC won't be much higher than if a level 10 PC went along. They'd still get the same XP and same XP reward out of it (say 200 GP / 200 XP). And you could have the script just say if they're higher than level 10, they only get GP rewards.
Furthermore, you could just open up the area
without the quest being enabled at all. What would that do to balance? The enemies would stay the same, even the boss potentially. Then what? ... how in the world does it unbalance anything?
And nothing stops a high level player from just giving people a free ride through all the low quests risk free. That's the key part here, quests of all levels need to have risk of some sort. Opening them to all levels completely removes that.
Isn't this already true for exploration areas? Neasa took Teuivae to the Crypt of Molander (or something) and if she wanted, could've killed everything completely risk free for Teuivae. So it's already something that's possible anyways. And Neasa could do a lot better and get Teuivae way more XP (if we were that type of player).
Anyways, I'm just not following the logic.
