15th Anniversary Campaigns & Campaigns +1

I mean, really

I wouldn't recommend pages, even with the campaign off, because it's so fast to kill every/anything with a pulse.

Especially since, at noob to AF levels, you will level up every other fight. With campaigns going, every fight.

As for fighting/camps:

50-54 - Quicksand Caves (kill everything)
54-63 - Waifu Woodlands (kill Lesser Birdies near Waifu warp)
64-75 - The Torture Isle (Kill reskinned sheep until 68, then kill squishy imps and flies near staging point)
75-80 - Inner/Outer Horutoto Ruins (kill either beetles, bats, or anything not slimy)
80-85 - Maze of Argus (kill bats and crawlers near Argus's den)
85-90 - The Only Reasons people come here prior to 75 are for THF AF and Choco Grass (kill anything other than Gobbies)
90-95 - Crawler's hell (kill anything in the basement where people used to camp at, the big circlejerk room)
95-99 - The Dragon Tree (kill anything/everything in the area where noobs got lost, it has the peapuks/crawlers/crabs now)

/kills the king of moogles.
