How is it possible?

[Sapphic]

Concept of having a "main class/role/job" comes from raiding and the limited amount of drops to divide between the raid party. Obviously it would be counter-productive to allow everyone to roll equally on every bit of loot. Outside of that, the concept of "main class/job/role" is just preference of playstyle.

The experience bonus is enough after your first level 50 that subsequence gained it much faster. Almost each time I ran a dungeon I'd gain two levels. I remember thinking one thing was holding me back from zooming to 50: DF queues as DPS. So I'd suggest looking for at least 1 healer or tank who wants to do the same, and queue for a string of dungeons with then, taking breaks for job quests burnout etc.

People use terms in this game however they want, whether they're right or not. I tend to agree with you, I never had anyone in WoW say something like "they're both my main spec". Main spec typically referred to what loot you would roll on with DKP, if you were REQUIRED to heal to make the fight happen you wouldn't be punished by not being allowed to roll on main spec gear. It was the class you wanted to gear faster. That doesn't necessarily apply to this game because of the loot restrictions though I guess.

This would matter if there was an actual gap between raid and group gear. But there is hardly one now (and not meaningful since you can easily clear 6-9 without being over ilvl 100) and in the next few weeks that gap will disappear.

Size of groups also contributes to it.

I still only call 1 class my main (cause it makes no sense to say you have multiple mains... there is always 1 your going to prioritize.... Simple way to get this answer out of people is to ask which class they are working on their novus on) but I have 3 alts that are fully capable of doing 6-9.

3 alts? Man, I've considered making a 3rd character and just can't bring myself to do it.

[Tashigi]

My main class is every class I have at level cap and play frequently.
All of my soldiery stuff is spread across a lot of classes.
If that doesn't meet your definition of "main" class, that's not my problem.

I play PLD in T6 and T7 and BLM in T8 and T9. They're the same item levels. So...I dunno what to tell you.

[Gormogon]

While I main BLM because I enjoy the overall playstyle. I could also main SMN, DRG, and WAR yet I don't because I don't like the overall SMN/DRG design and I prefer not to Tank for strangers and have to put up with their whining.

[SummonerSenah]

I main summoner. It's my best geared job and the only one so far with an ATMA weapon. It's also the job I use when trying new content for the first time. I substitute as a healer when necessary, though. I'm working on gearing up white mage now so that I'm at least i90 (currently at i86).

[Rennah]

I've got a full 8 characters and play all of them with different levels of frequency, but I can say that my "main" really depends on what I'm doing and what my party needs. I prefer different characters for different classes over dropping them all on one (strange for this game? maybe, but I like variety, and I've always loved making as many characters as possible in MMOs), so...yeah, it's pretty easy to have multiple mains. Doesn't have anything to do with ilvl, for me, they don't have to be exactly the same, it just depends on how often I play them. I know plenty of others in the exact same situation who wouldn't pin down a "main", either.
