About job gauge,
"Is it possible to get our buffs back when we disable the job gauge."
So far the job gauge has made a job allot harder to play then it normally would be cause we have to pay attention to yet another thing even if the gauge is big (and probably covering important stuff on your screen).
I know with the new system its hard to go back to buffs cause of redmage and other gauge like things you added with 4.0 but for the likes of scholar a co-healer cant see if you have any aether stacks or a (useless) fairy gauge to back them up.
Furthermore if you're really committed with the job gauge and don't want to go back to buffs please add DPS buff timer and other sorts to the HUD cause the meaning of the special HUD was to not make us look at buffs anymore but we still have to look there for any of our DPS buffs which makes no sense in that picture.
