Depends on the job.
Though if you have nin sub you can probably get people to take you to Yorcia(A) and get the Taeon gear instead of worrying about su1 stuff.
It's pretty easy to carry one, two, or even three people there on a 3/3/3 as long as you have two people who know what they're doing.
You could also just do the book, spawn the mobs, etc. But sometimes you need obsidian frags. You could just start doing it with a 1/1/1 or a 1/2/1 etc. It's not that bad honestly and it beats trying to grind CP/JP solo. I've soloed 1/1/1's to help friends who came back get some gear real quick.
As for CP per mob. The tier 1 zones generally give pretty low CP/xp per mob. You want to be farming/grinding in Marjami Ravine at least. You could also start in Yorcia, but I don't like the mobs there.
You're gonna have to look up maps and such to figure out how to navigate to these zones. Make sure to pick up the enigmatic device in Yorcia, as that is what is required to do the skirmish (It also functions as a one way waypoint).
