Looking towards 3.0 classes jobs and reflecting on 2.4 ninja + other melee you to have wonder why so much LNC cross class?
Well even though SE loves to lore us, even when it shouldn't be used (LOOKING AT YOU GC-FRONTLINES), it couldn't get around one blaring issue, TP. Though it would make more sense for jobs to, at times, use another job for X-Class support skills; the current armory system hinders this. Each class is forced to learn the same amount of abilities at the same levels, white mage recently got SSII which changes it a bit, which limits the "creativity" of each job's abilities but at the same time allows them to "save resources" by not having to remake essentially the same skill for each job.
What this means is, cross class skills aren't necessarily there to give us choice/variety. They are there so SE doesn't have to recreate a the same job skill in a different flavor for each job. Thus, each DPS that needed to regain TP was given lancer sub for invigorate and monk for recovery options, second wind. Mages have a similar issue when you look at them all having swift cast but that is impart due to the lack of caster jobs.
This effects us going into 3.0 because each job will not have a base class. (Though they didn't say it couldn't access cross class skills? *check this someone*) Meaning that if they need invigorate or swift cast will they end up with that ability in a new flavor? Could this lead to SE slowly removing "cross class" by just making each dps/melee learn invigorate as they level up ((idk around lv 30?), tanks provoke, and mages swift cast at that level? Will they change it so once we hit lv 60 we get a new job stone that takes away our ability to cross class and specialize further?
What are your thoughts on this?
It's not about removing, it's about phasing them out so that the current structure remains. Like imagine if SE gave lancer a new skill to replace invigorate, replaced pld's provoke, and thm a new skill to replace swift cast. Then they gave each DoW invigorate, Tanks Provoke, and DoM swift cast. Later on we get an advanced job crystal that completely remove all the cross class abilities and grants us more job skills. See where this is going?
P.S I'll proof read this more later as I am at work, on break, and doing this mobile.
