The fiercer battle was definitely the one of Gregor and Eini against the Goddess.
Others were trying to maintain some distance from then since the attacks were on such a huge scale that they might be caught by them. In particular, Eini's attacks were the ones covering too much area.
It wasn't that she couldn't control her attacks, but she was trying to get some enemies dragged into her attacks to give a chance to her allies to kill them afterward.
Gregor didn't fall behind with his attacks, but he wasn't as flashiest as Eini when attacking, so it was harder to notice.
The Goddess had already been forced to focus on defense. She didn't dare to lose her concentration anymore.
She was deeply regretting having used her trump card as a first attack, which ended up with it being wasted.
