It all really depends on how you use your fighters, the moves you chose for your fighters, and their abilities.
For an example on abilities, my Weekend Warrior Beowulf is 9,940 points, however, his special ability gives him final stand (among other perks), which can be helpful if I’m up against tougher foes.
For an example on move choice, I equip Peacock with Argus Agony and Impending Doom because that combo does a lot of damage to my opponents (ID first then AA).
It also depends on your fighters’ basic strengths (i.e. Painwheels all have a strong attacks, Valentines all have great speed, etc.).
