You asked me to write out three different intros in detail of all that they'd do, that's a huge ask lol. That's like having issues on a job or wanting a new job and then having them detail every point of the job, maybe possible but yeeeeehaaaaa what series of details. You may have wanted something more specific but that'd take me a long while to put down into words.
So I responded with the general "whatever was the target direction is what they'd leave you with". You don't need to know everything to avoid being lost further in the story. I skipped most of bard because I found it a bit eh, but read the last few and was fine lol (and I didn't get a guide to do it, something like I'm trying to upgrade/get skip potions to have a guide and short summary that can also hook someone in). Which I am trying to go away from skip potions as I don't like skip potions as they are - they don't have enough balance and investment hooks in my opinion, I know some people think we need a lot more investment but I believe many would be fine with a more grazing investment.. but currently skip potions have zero and I think that's an issue.
Simple since our competency levels have been abysmal since ever, pressing buttons is a strong start. I suggested many pages ago that you'd start out with your job at around level 30 and quickly remember up until whatever cap you were set to be at. Also many of the job quests don't teach anything anyways- which I wish they did, and the ones that are harder usually get nerfed down after complaints lol.
Also would suggest that the novice / intermediate / advanced halls are tied deeper into the game experience for all players (lower halls being great rewards perhaps but still optional, while extreme content requiring advanced hall completion), skipper players and not (slow burn lore readers too).
Anything that is DIRE info would be included, but there is a lot of world building info that isn't dire. Like Ascian is almost purely covered in just painting them as the bad guy, you lose so much little info but just making them "a mysterious baddy trying to revive Zodiark by sowing chaos" is all you need to not be completely lost (on Ascians).
