The real problem is with scrolls like Arise and Meteor I can literally count on one hand the number that have actually gone on SALE at the auction house. They're so mind-meltingly rare that most people who actually get the drop use the scroll rather than sell it on.
That's why you go to FFXIAH and look at the bazaar listings (apparently thanks to the Guildwork client stuff uploading the info every time you check someone).
Of course I was looking at that page yesterday (as part of checking on what Arise actually does) and it had to fall back to "nobody on your server has it in bazaar, so we'll show you the eight servers that do have one person selling it" mode. So yeah, it's still rare as hell. And PW is a lot harder to get to than Shinryu, and lots of people still haven't done the Shinryu fight yet. So it'll stay rare until something either makes PW easier to get the drop from, or something else starts dropping it.
But I still say it's a situational spell that does little more than give you a 4th Raise to help with people who are too stubborn to use RR items.
And then there's Meteor. In PJ yesterday there was some conversation about someone who had just gotten the scroll. Consensus was sell it unless you've got four or five other BLMs you hang with regularly for endgame events, since it's not so great alone.
