Which Job, in your opinion, has the biggest identity issue?

[ReynTime]

Bard was already mentioned a few times. I'll add AST because it plays NOTHING like its lore implied, and same goes for ACN and SCH since they're talked about in their quests as being all about "strategy" except ACN is the most simple job in the entire game and SCH lost actions that played more to its original fantasy.
DRK has almost nothing to do with Final Fantasy dark knight anymore. Its identity is now "the edgy tank".

- Squall is basically Rinoa's bodyguard (or... well, the knight to her sorceress, a recurring motif in FFVIII), so it's not that far-fetched.
- Gunbreaker weapons aren't meant to shoot bullets, instead they imbue the blade with various effects (consistent with FFVIII lore). That there are numerous actual GNB weapons in-game with seemingly functional barrels is... wrong, they shouldn't, yet they do.
- They do not use "Garlean" technology, not sure where you got that from? Gunbreakers supposedly predate the Garlean Empire by quite a bit, going as far back as the Allagan Empire... somehow...

What a stretch. Then I suppose rogue should be a tank since Zidane protects Garnet a lot more often than Steiner.
