I do think that it brings one problem with it and that's balancing the cr of quests through the week and across timezones to give all levels a fair shot at at least to get to a quest meant for them.
We already have quests limited by level, ie not 'open but you'll get less XP' but full out closed to someone not in a certain level range.
Isn't setting a level limit sort of like applying a CR to the quest? By saying, "These are the levels this quest is for," you are saying, "This is the range of monster, trap, and skill roll CRs and DCs this quest has," right?
I've always kind of thought the amount depending only on how long you sit through something rather than how difficult the challenge was, is kind of weird, no matter who you are or what level. But it most recently reasserted itself after Acacea was getting poison lessons from Triba and Pan noticed Tribs was only like 400k from level 30...and I said something like, "Hey that's only like 5 quests! You can totally do that!" meaning regardless of difficulty level.
And then I kind of squinted an eye and imagined Triba leveling to 29 by driving the Blade of Shadows through Bloodstone's back after her life full of destroying bloodpools and dealing with dragons and generals and breaking into the most sacred and protected of Rofireinite sanctuaries, the last big event in her life being the destruction of the villain that threatened the whole world and who killed the dragons, the 'new' attempt at a threat, or sent them shrieking into hiding... and leveling to 30 with a few quests about saving some villages or escorting some priests, or even dealing with the big scary awful dragon threat that the previous threat scared the pants off of... solely because they were of the appropriate length...My brain just got kind of boggled, you know? Gulnyr and I were joking a little about the server imploding when Acacea and Jennara reach Triba's level because it just feels weird, even though our characters have been involved in some crazy things. And it does, at least for me. Because I'm still playing, still going on quests (even if they will never again be quests in which she is the healer at the Bloodwell or another quest in which she is in the presence of a goddess), and still getting full XP for my time, regardless of what level it is or if it's really a test of her abilities.
Should it not be hard to find new challenges once you get to a certain point of mechanical level power? This brings me to something else that I have been turning in my head regarding the new game, so I'll have to make a new post about that or something...
