you should not have to play a job you don't want to in order to progress story wise...period
I agree op 100%

it will be a huge huge problem down the road for any new players if SE doesn't stop gating story advancement behind these dungeons.

an alternative needs to be developed by se , I seen this as an upcoming issue a longggg time ago. and although I wont personally be affected by it, it definitely is something se should be altering its design for soon.

its a bad design flaw imo, gating is bad...in any game and se is famous for it in xi and here as well
