Gildarts was always tiers above the GOI. They literally can do nothing to him. So if wherever you put GS you have to put Serena.Nah, as @aymen24 pointed out with panels, Gildarts couldn't just finish off Bluenote as he pleased. They were fighting off screen for quite a while, it was a drawn out fight until Azuma did what he did. In the end, Bluenote used his strongest attack, Gildarts countered it, and Gildarts used his 2nd strongest attack (strongest attack shown at the time) on Bluenote to finish him off. It was, by no means, a stomp. It would've been a mid diff, which got turned into an extreme diff by Azuma.
We know that all the GOI are several tiers above x791 Jura (we don't know where x792 Jura stands), from GMG arc. And Serena is several tiers above the 2nd strongest GOI. God Serena >>> Hyperion >>> Bluenote/Jura
God Serena went to Alverez because the empire's aim coincided with his aim, which was Acnologia.
I mean, I agree that's the way things are. After all Mashima is writing. Like I said before, I don't even contest the power levels of the relevant characters, I'm just saying it makes no sense logically
They had a small fight then Azuma did what he did. Bluenotes strongest move (Blackhole) was fodder to him.
Gildarts was always GS tier (whatever that means).

And finally, his character arc... I used to be blind to how much of a simp he is coz I liked his magic. But there's nothing for me to latch onto in terms of his character, nothing that inspires or interests me. His might be one of the more lackluster redemption/guilt stories I've ever encountered.
