First, sorry for the necrobump but when something is said in a definitive way I can't rest until I address it.
Second, they could be related:
SourceGamer Escape: There was a tame ability mentioned as well, so does that mean Beastmaster as well?
Yoshida: Yes. The foundation or system for using pets in battle is currently being made. So yes in the future there will be a beast tamer type of class. Again, it’s all about that adding one class means adding more jobs and all these extra things. So all these jobs won’t come at the same time. It’s all about the priorities, but it is on the list and we are making preparations for it.
Like one idea could be for example maybe having a beast tamer class and that job would be like a summoner type of job.
