I don't understand BLU defenders

[Beckett]

Is it an FFXI thing? That's one of the few BLU versions I have not played. Are people basing this purely on FFXI BLU?

The XIV devs have always seemed to have this idea in their head that the only possible version of BLU was the version from FFXI. XI's BLU could learn literally hundreds of spells and mix and match them to fit any number of different situations. For example, while they were never the best at it, they could re-arange their skills to be a tank, or a healer. That kind of versatility obviously doesn't work in a game like XIV. Of course, XI's BLU is far from the only version of the job, so I have no idea why they were so dead set on it being the only option.

Maybe people are tired of cookie cutter classes?

If that was the one and only reason they gave for why BLU was a solo class, I'd be a lot less salty about the whole situation. Every excuse they gave for why BLU "couldn't possibly" work as a regular job rang hollow.
