1) I don't bring Jean down. Bringing a character down means you try and scale them back from power levels they have demonstrated in canon. I merely use canon to accurately state where Jean's power levels are.
2) I am not saying that Storm has to be the focus of every single story arc, but the way she has been written in the X-Men books for the last decade is abysmal. So, yeah, I and other Storm fans are going to complain about that.
3) Sure, Guggenheim gave Storm this two-parter, but he did so in a way write the character down by ignoring the awesome forward development Coates gave her in Black Panther. What's going on in Gold with Storm is trash.
