This game needs depth, Please implement a second weapon (playstyle) for each job

[ShinkuTachi]

XI did this right. Jobs could use a range of different weapons, weaponskill was independent of your own level, you chose what to master and how fast.

Eh, that's only somewhat correct. Only Warrior could use a "range" (ie: many different weapons); however, most jobs could use a few. This sense of depth or variety was simply an illusion though, as every job specialized in only one or two specific weapons. You couldn't just use whatever you want on any job and achieve equal results.

I think Darknight, Beastmaster might want to have a word with you. To a certain extend als Bard, Samurai, Thief and Ninja

War could pretty much use every weapon in the game, all other jobs could only use a handful.
Also, most jobs could only skill up a certain weapon or two to the point that a DRK, for example, could skill up a Scythe and a Great Sword. So I don't understand what you're trying to refute here.
