I wish with G'raha that they'd gone a different route - I agree that he seems to have too many similarities to existing Scions (I feel his role is pretty much covered by Urianger and Alphinaud - the only "niche" he seems to have is the Allagan blood which they've relied on for two patches now).

I would have rather his arc been that due to his efforts on the First - building up the Crystarium and summoning the people who would save the shard, including his role in that - that he would realise he's a hero in his own right, and that while we were still his inspiration, that he's ready to go off and have his own adventures. I'd have loved to have seen him thank us, and go off to strike his own path in Eorzea.

Then he could have come back into the story at points where it makes sense to have him there, which would be a fun surprise for his fans. As it is I feel like he's just sort of... bloat? He was far more tolerable in 5.5 I felt, but he didn't really add anything.
