It will never be Scout (or Rogue) => Thief (DPS) or Ninja (DPS).
Why? They'd play exactly the same as each other. You can't differentiate jobs from each other with only 5 skills considering majority of your skills are from the class. So it'd be something like;
Scout => Thief (DPS)
Wanderer => Samurai (tank) or Ninja (DPS)
That way you can make them different enough so that they don't play together. Not to mention if you had Scout go into Thief / Ninja, you'd run into animation problems since Thieves only use 1 dagger (and attack multiple times) as opposed to Ninja (who just has 2 swords/daggers/etc). Kitru made a good post on it a while back.
Since my daily post limit has been increased to one post every 3 days, I'll just edit this one.
Look at classes like Arcanist, Conjurer, and Pugilist. They are just Summoner, White Mage and Monk with different names. Just because. So Scout would just be Thief without cool job skills.
The only issue I can see with Samurai and Ninja not being from the same class is why I believe dual wield classes will not come from single weapon classes. Remaking animations for all skills is very annoying and really a waste of time.ok, i need to react to this one since it go way to far for explain an idea that a no go...
Samurai =/= ninja, you can't get them from the same class.... a samurai will use a Katana or a nodachi (two hand katana) while the ninja will use a Tanto (dagger version of the katana) or a wakizaki (short katana).
that said, generally in Final Fantasy series the only difference it's the dual wield for the ninja with the use of the ninjutsu+throw against multi hit+steal for the thief. (and it's not always the case for the multi-hit)
This is where you misunderstood. Thief used to attack with 1 weapon so in ARR they would use only 1 weapon to attack with. In previous games they just attacked multiple times, which is fine. Ninja uses two swords. Now, follow me with this; the animations for these weapons will not be the same. This is where this notion falls flat on its face. So Thief shouldn't be connected with Ninja solely based on that.now, nothing forbid them to make the thief get dual wield and lose multi-hit since it potentially the same stuff! instead to use 2 weapon, you hit 2-3 time. that said, you seems to misunderstood some point, the class is generally based on the weapon, teaching you how to use it. the jobs give you special tool that goes with this. for make it short..
They'll need to introduce another 10 new skills (L60 cap) before you can sufficiently differentiate jobs from each other if they the same role and come from the same class. Let's take a look at Archer/Bard for a moment. Remove all their songs and what are they? An Archer. Do they use songs all the time or even Rain of Death religiously? Nope. So if you were to make Ranger, a dps class, how would not be exactly like Bard in practice? So you can see how doing that within the new few levels won't work.Rogue (or whatever they choose as name) give you the weapon skill for use 2 blades at the same time:
- Thief, teach you the art of steal
- Ninja, teach you the use of the ninjutsu.
your skill with the dual wield will come from the rogue class while your jobs will give you more...specialized skill.
now, you mark a point when you say that jobs are hard to differenciate from the class, and that the main reason i think they need to add more level before add new class and jobs. for give to the jobs more skill and make them really different.
Two-hand can easily just be a stance. Considering the staple of Samurai is Fdraw, Iaido which is one handed.ps: for the samurai will come from the two hand sword class, it's seems more logical and will allows him to wear the right armor, since it will be in chain mail or heavy armor, when the ninja it's in leather armor.
