Disc. 1

Right now I´m trying to build my characters´ Limit Break levels.
I´ve just finished the Rocket Town event and I´m right now slaying tons of enemies in order to build those Limits.
I know you are able to fight formations of six Battery Caps in the forest near Rocket Town, and yeah, that may seem great for this kind of training.
However, those battles are SLOW, and my relatively weak characters get beaten up a lot, so it takes lots of time and I fall asleep, *yawn*.

So...

Do you know where you can fight the highest amounts of enemies _in shortest time_?
Not just places with the highest formations, but places where you can actually defeat 60 enemies somewhat fast.
