How many only main one job?

[Kakerziam]

I main BLM, but my secondary is WAR. I used to raid with BLM in 2.x and Gordias (and quit at A3S because good lord man). It's more of a "I'm just really good at the job" than anything else at this point, but WAR I find actually fun because I don't have to worry about Enochian+Astral/Umbral all the time. Gearing two jobs at the same time is hard, rest in peace whoever likes playing 3+ Jobs.

I only main 1 job. Mostly because I am not much of an Alt person, even when FFXIV lets you play anything on 1 character I find it hard to do something else. -hehe-

I main a drk unless duty finder requests a dps or healing in need than i switch to ast and blm

[Aomine1992]

I switch a lot too with DRG being like my main class (Lore gear) for raids besides that I play SMN, BLM, NIN, BRD, all three healers and DRK lol but I make sure I have 1 healer, 1 Tank and 1 dps geared up incase I need to feel In where any of my groups need it...in high level content

I only main Ninja, I have Dark Knight at 60, but haven't touched it in quite some time. Before Ninja came out I mained Monk, I really prefer fast paced classes.

[Arkenne]

I main NIN, but Im currently gearing up all jobs but healers simultáneously, specially the Tanks... because I can...
The fact that crafted gear is on par ilvl wise with Midas gear has helped me a lot for this.

I main MCH, but I used to main SMN. I tried to play both of them but it was too much of a pain to gear them both up so I dropped SMN.
My SCH is pretty well geared too but I only use it if a friend needs a quick roulette since healing is stressful in DF.

I main WHM and just need one more item to complete My ESO set. I also have a Lore ring. I'm going to upgrade to Lore gear for this class.

My sub-class is Summonr/Scholar so will be working on Summoner next. It's still level 50 but almost 51. I love pet classes so it's a good subclass for me.

After that I will level AST. By the time that is 60 I will probably have all the Lore healer armor and accessories.

Previously I also leveled PAL and BLM to 50, but I honestly did not enjoy playing either so I do not think I will level them to 60.

I have BRD at 39 and I do like this class, but torn on bothering with it because I don't feel like levelling Dragoon for cross class.

Classes that aren't for me, so will not cause me any gear stress: WAR, DRK, DRG, NIN, MNK, MAC.

*UPDATE*

I started the game during beta phase in 2013 as a CNJ. By end of October, I had become BRD as I thought it was going to be huge on support like the FFXI's version. I bounced between WHM and BRD until I ended up being a BRD main. However, since I was a NIN as a tank in FFXI, I became a ROG/NIN when it released in this game.

Moving forward, while I'm still officially a NIN sitting at iLv223, I have never been dps-savvy in MMOs; mostly support, tank, healer, in no particular order. That said, I am now shying away from NIN to focus tanking. While I have been rolling/gearing PLD, I now found DRK is more my speed with it's crowd control, enmity generation abilities, and it's aggressive style of play.

My DRK has not broke high dps numbers, but I'm taking baby steps to fully learn the job before I'm 100% comfortable with pushing dps. My struggle with DRK was with being main tank on Sephirot, in regards to me dying to the fourth tank buster in phase 1. Now that I have that under control as of last night, I'm pushing to gear DRK, who's currently at iLv214. I had PLD/DRK as raid while NIN was everything else, but to get better at a job, I need to be on it more, so I'll be on DRK a bit longer.

So, while NIN is considered my main, it may end up becoming my alt while DRK become my main. I recently joined a static group (finally) who wanted me as tank (PLD preferred), but I've been going as DRK. And since they're ok with me being DRK, coupled with me wanting to play DRK anyway, it may become my main.

When I am ready for a static, I will main WHM but outside, I play every healing jobs depending on my mood, and dungeons. I SCH when its roulette level 50 and leveling. Trials is WHM and 60 plus expert I go AST. I dont really have a main healer outside raid but right now I focus on WHM since I plan to go in a static with that class.
