Glenda until now has had basically unchecked power... she's the most powerful member of the cast. Moving forward I have things in the plans that someone like her could have snapped her fingers and "fixed" but I didn't want that to happen as it's awful for storytelling and I didn't want to not have her in the comics... so when the opportunity came for me to dial her power level down and have it be for an excellent reason I took it as kismet. Eventually she might be able to adjust to her new emotional state and become super, duper powerful again, but until then we get to have Glenda in the comic and I get to tell stories with consequences.
