help? 100% div card farming efficency

SSF - no trades

I've been doing the whole shabang, rolling maps, vaaling them, using sextants, running harvest to swap scrabs to keep running div/ambush scrabs and I have +55 quant from gear.

I would very much like to just chisle +Alch and go.. more maps/hr. should offset the time spent preping juiced maps??

I was thinking maybe something with Wandering path + Singular focus and taking all the quant nodes on the tree and just zoom through the map with TS, however this is the 1st time I've ever tried to make an MF style build and would love some advice on how to plan out an atlas tree.

I do NOT care about rarity, I don't want MA, I just want Divination card drops.

does no one spec 100% for div cards? is WP bad?
