Ned some wisdom here.

My problem is I can't decide on what job to level. It comes from playing FFXI, I had a 75SAM and 75SCH. But do to joining the game late and having no money the only way I could endgame was go as scholar. Don't get me wrong I don't mind healer(it has it own rewards), just don't wont to be stuck in that role for EVERYTHING my whole game stay.

Just that memory of FFXI got me stuck not leveling nothing, just farm then log out. I just don't want to be stuck with playing only 1 job like before. Well the jobs I'm interested in are DRG/SCH/MNK ATM. I have BNT and WVR at 50 if that matters any. Any advice will be appreciated.

It's not on your list of options, but you may want to consider SMN since leveling Arcanist gives you access to both SMN and SCH. It is a damage-focused Job. You don't have to level them separately either.

Really it comes down to what play style you enjoy the most. I started out as a DD class..but in every MMO I always end up as a tank..sure enough i'm a PLD now. Do what you enjoy not what you think may be more economical or quick to level because you'll just end up switching later and wasting your time.

Personally I always play as a tank. I personally find it fun, but there is almost always a shortage of them which means you make friends quickly, and are invited tongroups often.

With the job system being so open, I'd recommend taking one class from each starting area to 15. Try the different styles and see what you like the most. You could do somethign like WHM, MRD, and PUG. I've personally found that I like different things for different reasons, especially crafting. If you are not in a rush to get through the main story, there is alot of fun to be had casually leveling up multiple classes at that same time.

I had the same problem where I have a 34 WHM/30 BLM/and 39 SCH/SUMM, and also on a separate character a 32 Bard. I finally went with my Arcanist because when I solo I use my Summoner dps (well as much dps you can get with MIND as the main stat) character, and my Scholar in dungeons. Has worked good for me so far, though I will always be an altaholic.
