Do you think it's possible

[Onyxia]

Leves are good, but they are finite, while collectibles are not. Leves are best for ALC. I did not even touch his collectibles. All other classes I leveled with collectibles mostly. Plus moogles quests for additional exp.
GC turn-ins I did only for crafts with * (double exp). Of course you should try craft HQ for x4 exp.

I leveled all to 60 in 2 months. And made 250 millions gils in another 2

To get 4 crafts to 60 by the time stormblood comes out?
They're all at 50 but seeing as how I have 3months I think I can get it.
.

easy, I had nothing in November and got them all to 60 in January i think? don't remember.

And that was done with everything that has been said here, just though leves, GC turn in, and moogles.

Definitely, I did all of mine it in about two months. Do moogle quests, GC turn ins and leves. Should take no more than a week per job honestly.

[ZioSerpe]

Moogle quests every day, more than possible, it takes about 2 weeks to go 50 to 60 with only those... Hell I have all but 3 crafters at 60 and I never crafted a single thing for leveling, ixials to 50 moogles to 60.

You can do the following:
Always: Daily GC Turn ins and Leves
1-50: Ixhal Tribe Quests (some of the higher level ones need you to have a Battle class or gatherer at 45 thought)
50-60: Moogle Tribe Quests and Script turn ins

Actually you only need a battle class at 45, which you have anyway, you need a battle class at lvl 45 to unlock them in the first place, for gatherer the nodes are lvl 5, so even if you're level one you can still do them.

Every little bit of exp counts and, as such, I would advocate still doing Ixali through to 60 every day as well. It may not be the biggest chunk of exp, but you still get the reward for turn in plus the easier HQ exp from those quests. You get 9 Beast tribe allowances per day, you can spend 3 on the Moogles, that leaves you with 6 you can use for the Ixali.

Yes, always do GC turn ins and once you're high enough, grinding collectibles is great for experience and gear.

[Reinha]

All you need are Moogle quests, challenge log and GC turn ins. Level the jobs equally so you can use GC turn ins every day on all of them. Levequests are not needed but if there's nothing else you can use them on (like the Anima) then ofc use them up.

[Yeol]

All I know is moogle beast tribes or ixal
Please dont say leve quest.

They are the way to go if you don't want to spend gil.
Leves are fast if you have a friend helping you.

Now, the fastest way to level all 3 of them in one day is collectables. But that requires a lot of Gil (Talking in millions).

Leves are the easiest and unlike 50-60 there is no running, you stand in one place picking up and turning in. It only takes about 70. I finished 5 crafters in the past 2 months paying for kits. 1.5 mil a kit, i made more gil than i spent by the end. I don't know why anyone would be against using leves. Its like asking to ride a bike but remove the wheels.
