Gunbreaker and Dancer:
Are literally incomplete jobs. They do not have access to glamour items, available to 100% of existing jobs. These jobs also were not released at level 1, so you cannot even level them, the only things compariable to other jobs, is GNB's tank achievements and rewards. Outside of level 60 and above, these jobs fall flat and hard.

I'm not sure you know what "literally" means. They're complete--they're just not complete to your likings. It is not new whatsoever for MMOs to release jobs that don't start at level 1--fact is, the vast majority of players would not want to start these jobs at level 1. If you're excited for the next expansion but want to play a new job you wouldn't want to have to grind it all the way to 70 before you get to play new content. DKs in WoW started at level 50 in WotLK IIRC.

As far as glamour, yes I'd like if they had more glamour items and yes I think the reasoning for them not having Ifrit/Garuda/Shiva/Titan items is dumb reasoning, but them not not having those glam items doesn't make them incomplete. Do I think it's lazy? Absolutely. But that doesn't make the job incomplete.
