Rooks would have to recode the AH side (then be pushed by Scragg) to take updates from data scraped from guildwork. At this point he'd be better using a standalone scraper for ffxiah as guildwork is dead, but that's a matter of opinion.
Achievements were once on Rook's big dumb list of things to do, but he's been busy so it got pushed to the wayside. At this point pray for him to take interest in it/find time or make your own site with achievements/progress/addon to scrap data/blackjack/hookers.
