If you'd rather ease back into the game by soloing/duoing, here's what I did to get from 10-80 in about a week (mostly solo). This also gives you a decent amount of starting gil from crystals and misc drops.
Using DNC/* or */DNC helps immensely when soloing melee jobs, as Drain Samba/Curing Waltz practically eliminates downtime - so even if you don't plan on taking it all the way I'd get DNC to at least 49 for use as a soloing sub.
Read up on Grounds of Valor
. I used This list of pages/locations and level ranges
as a reference.
When doing Grounds of Valor it's best to stay in one zone until you're done there as the EXP bonus increases each time you complete a "set". That means it's better if you can stretch your stay in one zone for as long as possible instead of moving camps every few levels. You also lose any built up bonus if you zone, so make sure you have enough food/bag space before heading out. I also recommend getting field support: reraise (or using reraise scrolls) to avoid having to return to home point if something should happen.
Keeping up to date with gear isn't as necessary as before, especially since you'll be outleveling any upgrades way faster than you can resell your old gear - but make sure you have decent upgraded weapons for every 20 levels or so.
If I've listed more than one page in a zone, that generally means move on to the next page when mobs start conning "Too weak". The following pages require little running around and pretty low aggro risks.
1-15 Any starter zone
, use an emperor band and just kill any easy prey you see.
15-23 Dangruf Wadi
23-35 Maze of Shakhrami
35-40 Lower Delkfutt's Tower
40-49 Upper Delkfutt's Tower
page 1 (The hallways on both sides of Mimas, take the Delkfutt Key elevator then exit the first room). Stretch to 50 if possible.
50-57 Crawler's Nest
page 1 (if this is camped, Garlaige page 2 is an alternative. Roam or camp by the first gate)
57-64 Labyrinth of Onzozo
page 1, stretch to 65 if possible.
64-99 Quicksand Caves
page 2, then 4 when you're comfortable roaming the room (Anticas stop aggroing at around lv70). Use W. Altepa (J-9) entrance.
EXP/hour using this route starts out at about 12k in Wadi then steadily increases. At 80 I'm getting about 40k solo, 45-50k duo.
This is as BST, non-pet jobs may increase at a slower rate - but any melee job should be well into the 30k range.
Note that some zones (esp. from 40 on) are a bit slow at first, but when you gain a couple of levels you'll be killing a lot faster. Edited, Aug 10th 2012 6:30am by Ske
