Grind Camps

[AeraLucis]

EDIT: I want to add that a lot of people are saying that they're running out of Young Raptors going in at the early 30's. It may very well be that this camp, given the range of their ranks, it be best to go in 35-39.

Now I'm confused. Wouldn't going to the Raptors with a higher rank party make them run out even faster? If people are running out of Young Raptors in early 30's groups, then shouldn't they go there at a lower rank so they last longer?
Or better yet, go to a camp where the mob's respawn rate is short enough for you to not run out?

I was under the impression that if you've run out of mobs and have to sit around for repops then you've already lost the SP/hour battle.
