That i delevel BLU and level it again from the ground up?
You are already 95. Why suffer through that again?
That no one should ever level BLU in a Abyssea PT, and should instead content themselves with the 6k xp/hr that soloing brings, because "Thats the right way to do it!"?
It's not about the right way to do it. It's about they way learning BLU spells works. It's not based off your level - it's based off your skill. Trying to learn a level 95 spell with level 1 skill is impossible. It just doesn't work. As such, the suggestion is to learn ALL of the spells because:
a) As you start at the bottom, you'll start with the spells you CAN learn.
b) This will give you spells that you can spam in order to boost your skill. Use the spells as you get them on the next mob you are trying to learn from until you get Bludgeon. Use Bludgeon from then on (cheap spell, decent damage, can skill up a little more quickly than normal because it's multi-hit) along with any others you want/need to use.
c) You'll learn a lot about your spells and job traits by playing around with the spells you learn.
d) You have an added advantage that most of the spells you will be learning will be easier to get because there will be many MORE TW mobs to learn from.
BLU is so.... personal. What you set and what you use varies greatly with how you play your BLU. And, unlike most Hybrids, because BLU is forced to specialize, it gets the ability to be good at what it specializes at.
The suggestions are good ones - you'll learn a lot about the job by listening to what they say. Don't let the elitism of the responses (or the knee-jerk reaction from us old vets) get to you that much. If you care about BLU, you'll master the job. If it's just to be a "Proc-whore", then you'll get exactly that out of it. But, you're going to have to start somewhere, and you're going to have to learn some of the early spells simply to be able to get the others.
One final word of advice: Max blue magic merits. This will help you get spells even quicker, since they do calculate in to your skill at the time that the "learn chance" is rolled.
