Both sides struggled.
However, Eren's enemies had it worse.
It was very tough to fight elemental spells with mere weapon attacks alone. Most of the participants hadn't even invested enough Karma points in their defensive gear. As a result, the participants were finding it difficult to completely overwhelm Eren with their attacks despite their sheer numbers.
The participants who remained inside the event till this point were a patient bunch. They knew how to wear a bull down by making him run all around the pit. To expose Eren's chinks in his armor, a high-intensity clash was maintained by all the participants who faced Eren in multiple batches.
A cacophony of screams and curses was constantly being heard on the battlefield. However, all the butcher could hear was the sound of his own heartbeat.
