Warp scrolls are 10 cp, warp cudgels are cheap, homing instinct..

Although warp scrolls are a nice substitute, I feel this area can be expanded upon.
He knows there are warp scrolls there. That's not a reason to say it can't be added to other jobs. I think it wouldn't really be a bad idea to give RDMs and SCHs the spell (And maybe GEO when it comes around). The only function these spells serve is convenience/running away so it's not like it's that big a deal if I can warp when I'm on RDM/SCH.
