Was this a mistake? The Eden striking gear is literally healer gear in appearance. The healing set is exactly the same, just white. If any other job got that, it seems like it would be more appropriate for casting or aiming.
The aiming gear looks like it was meant for striking gear instead, and at least the "healer" gear that striking got would make sense for a dancer to wear.
It would be nice if striking could just get a single tier where their gear didn't look like garbage for the jobs it's supposed to be used for. I wouldn't be running around in a dress trying to fight as a monk, it makes no logical sense.
