IMO the biggest issue with RUN atm is the gear selection... The choices, especially for a "tank" are absolutely deplorable in the lvl 30-60 range... The main cause that I personally believe is responsible for this is the lack of "Chain Armor" options. RUN is suppose to be a tank, at least that's what I keep hearing... Limiting them to Scale Armor seems a bit questionable at best... Ninjas can even use heavier armor than them...
Proposal: Introduce some lower level job non af specific gear (like every other class has). Allow RUN to equip up to Chain Style Armor.
