I know yoshi-p stated he wanted to do an original class. I also know he stated he was thinking of 5.0 taking place in garlemald (at least I heard he said that) so I think the next job should be a legate/officer type class. Something like Nero and baelsar. Personally I think it'd make a good tank and utilize wrist guns/gunblade and maybe have a similar playstyle to red mage but opposite. So using melee to build a heat/bullet gauge to then on the gunfire. Itd also be a good excuse to finally give us some of that sexy armor.
