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

Do you have proof of this speculation?

ya, it was announced in the live letter on youtube live if you watched it for e3. maybe not in this coming xpac but Yoshi does state they are looking in to making multiple roles to each class. although I will say im not sure if by second jobs he means roles ie tank healer dd but this was discussed and they want to add additional roles to each job.
