It's not so black and white in reality though. There are the main subs that most players use for certain tasks, but there is also a lot of variety that the subjob system offers.
I didn't argue that in theory it offers a lot of variety. I argued that in practice there isn't much.
For example, going all DD may not always be the best way to take when doing certain things. A drk might want to sub /dnc or perhaps /whm
In Campaign, maybe. A DRK that showed up to an XP party /dnc or /whm would not be highly regarded and might even be called gimp, unless there was a specific need for that DRK to have healing abilities. In that case, the party might have bigger problems.
as well as /mnk for those zerg situations where +hp makes a difference.
The average DRK may never see this situation anyway. You are correct that it's a situational sub, but we are talking about the majority not the minority here.
A drg still needs /whm or /sch for reraise if not anything else.
No, they don't, and if you do a /sea all of DRG on your server right now the majority is going to be on /RDM or /BLU. Reraise is a pretty silly argument when the other two subjobs offer so much more that would be useful to a soloing DRG.
Corsair may want to go /rdm for the added MAB for quick draw.
I don't profess to know a whole lot about COR, but I wouldn't be inviting one to a party who was subbing RDM, and especially not WHM.
SAM can go /Thf if there is a need for extra TA.
So /WAR and /THF is a whole lot of variety? Two subs, for one job, for 75 levels. That's my point. There are only a couple
realistic options for any given job, and some of them don't even have that.
PLD can choose to go /war to exp if tank is needed, but also /nin for dual wield or /sam for greatsword DD'ing
Why would you invite a paladin to a party unless as a tank? Sure if there is no other DD looking PLD is a last resort choice, but it's not usually like that. I can count on no hands the number of times a party leader invited me to a party and said, 'Oh, by the way, you will be DD'ing, what's your GS skill and do you have /SAM?'. It's not realistic, and I did say that the options had to be realistic to be arguable.
And for the record, nobody goes anywhere /nin for Dual Wield. It's done for damage avoidance and Paladin can't really pull off /nin and keeping hate until end game. It wouldn't make much sense in an XP party unless there was a setup ahead of time to put together an SATA and etc, and that's part of my point: certain subjobs make more work for everyone involved and that's why people can't be themselves and use them
or even /whm for main healing.
This I honestly just laughed at. Maybe
, if you are a taru you could get away with this, but again we have to talk about realistic options here. If any paladin can say with a straight face that they were invited to a party and asked to sub WHM so they could main heal, I will be extremely shocked.
Of course some jobs use just one sub most of the time, but even they have other options for some events (a rdm can go /drk to be able to stunlock a mob if needed, etc)
RDM is an exception to the rule in that it's the one job who truly can be versatile and do just about any role in the game, however, in group situations you still have only the standard subjobs. End game groups want you /drk to stun lock. XP groups want you /whm to heal them. And then there is the ever popular /nin for solo. I have seen some RDM's going /SCH to some things now but most are sticking to the tried and true.
What about SMN? There is only one subjob for those poor guys. /WHM or you might as well just pack it up. The job system is far too dependent on the subjob system, and more to the point, specific subjobs for the main job to be an effective part of a party.
And the final issue is that folks might not even like
these jobs that they have to level in order to play their main job effectively. The story of the guy who only wanted to play as Bard keeps coming up, in that first he had to play whm to 30, unlock bard, unlock nin, level whm further to 37, level war to 18, level nin to 37, and then he could finally start leveling bard. Everyone else's stories are pretty similar. A better system would be one in which we play and enhance the main job we have chosen
, instead of having to backtrack over and over to level things we don't even like. That's part of the reason XI has such a bad reputation. Is that really what you want for XIV?
As I said, it's a system that was a really good idea in theory, but in practice, fell short of the mark.
