GE- With ARR we’ll see Arcanist added with Summoner shortly after the game launches. Are there any other classes or jobs you’d like to see added? And will these be added in patches or expansions?
Yoshida- What I would like to see right?
First of all, we are planning a new race for an expansion pack. For the classes and jobs, we will introduce them through patches because all of the Legacy players have level 50 jobs anyway. When we introduce new classes and jobs we will probably increase the level cap at the same time.
About what I want to introduce- it’s more like what I think I have to introduce. Something related to guns because the (musketeer) guild in the game. Something related to that I think I have to introduce.
Also I do feel that scouting classes are lacking so I want to bring in Thief, Ninja and those that have to do with stealth. Also more casters like Blue Mage and Red Mage are something I would like to add.
Whatever the players want, I want too.
