Sure, I get that. But if you have "limited BLU" versus "unlimited BLU" as basically functionally separate jobs,
and you have to strip away everything that basically makes blue magic "blue magic" (e.g., learning the spells by seeing them cast) in order to make it play well within level roulette... why not just make a different caster? Instead of a broken blue mage stripped of its blue magic identity, why not come up with a
different caster that has some identity that works better in roulette?
Or, to put it another way: if, in order to make BLU work in normal play, you have to...
- Ensure that BLU learns spells at specific levels like other jobs (rather than learning them in content through observation), so you can guarantee that a given BLU has the necessary spells (rather than joining Roulette at level 63 while only having Water Cannon).
- Strip out the spellbook functionality, so that you can guarantee a given BLU DPS in a roulette has the necessary skills to function at that level, rather than some custom spell-set that doesn't work. (Who's going to want to wait for 15 minutes while a BLU tries to shuffle their spells to something appropriate to whatever they got in roulette?)
- Ensure that BLU syncs down in roulettes, so that (for instance) you don't have 17 AoEs in Sastasha while the other DPS has precisely none.
- Limit BLU to the DPS role, rather than allowing it to tank/heal, so that roulettes can role-match in a sane manner.
...then I would ask, what exactly about blue mage makes you want to play it in normal content? This is not a facetious question, I am
genuinely curious; to me, all the things that would need to get stripped out to make BLU work in normal content would be most of the things that I
personally feel actually make BLU... well,
BLU. As opposed to just another caster?
Yes, it's possible they could basically define a set of spells from the BLU spellbook and just give them to you at various levels, and turn it into a normal caster; mechanically, that's
possible. But what would give BLU a separate identity from any other caster at that point? What would make it worth making one of the two jobs in 7.0 be "BLU with a set spellbook where spells unlock automatically level by level, enforced DPS role, and with all the weird buffs/debuffs that would make balancing high-end content (like Savage or Ultimates) incredibly difficult if they had them", as opposed to some other caster?
Personally, I would prefer BLU remain BLU -- and a limited job that
can be all the weird things -- and just get another caster. Because if you've split BLU into functionally two jobs... what's the gain? This is a genuine question, because I don't understand what it is that people actually want out of "second BLU".
And you
would have to split it, realistically, because 1. existing BLU needs to be able to learn spells in the overworld, but you wouldn't want someone advancing the MSQ with that, and 2. you wouldn't want someone able to power-level "unlimited BLU' via "limited BLU"s absurd overworld XP buff. Among other things.
(I mean, this is leaving aside the fact that if they
did make "unlimited BLU" one of the two jobs for 7.0, I can just
imagine the howling on the forums about "that's not a
new job, they just took an existing job and stripped all the neat stuff out to give us another caster DPS! That's so lazy! We should get a
third job!" or whatever.)
