Party of 3~5 @ r15~20 -> Iron Coblyn (r30~34) inside Nanawa Mines in Thanalan (27,20) about 8 mobs near the aether. More mobs in back of the mines, but careful of Djiggas.

DUO @ r19~21 -> Amalj'aa Drudge (r28~30 lancer) at Amalj'aan Altar in Thanalan (40,32) about 5 mobs.

unattempted r19~23 -> some type of humanoid mobs (r30) in Cassiopeia Hollow (11,6) like 15+ mobs. agressive.

Party 2~3 @ r19~24 -> Amalj'aa Grunt (r30) and Amalj'aa Striker (r32~34) at Amalj'aan Encampment in Thanalan (47,27) about 10 of each type of mob!!! (20 total) GREAT CAMP.

unattempted r28~? -> Quartz Doblyn (r40~44) in Thanalan near Camp Broken Water. see map: http://ffxiv.yg.com/npc/quartz-doblyn?id=3102107

unattempted r33~? -> Assassins inside the plateau near Amalj'aan Altar in Thanalan (40,30) about 11 mobs

the ones listed above I found myself. Those that say unattempted are obviously because I never partied there myself, but they appear to be good places and someone should try them out and report back. Also please note if you are looking for a good camp so not just look at the rank of the monster. humanoid/beastmen type mobs tend to give more sp in my experience. For example, I could solo r30 amalj'aa at r25 and get like 250 sp. but if I soloed a dormouse that was r37 I only got 100sp.
