Here's why having a (relatively) balanced ATK/DEF helps out in Colosseo (this is copy/pasted from the Colosseo section of the wiki):

===Life Points===

The player that has their Life Points completely drained first automatically loses the battle. Each attack made in battle drains Life Points, with the exact amount dependent on Attack Line damage and Defense Line defense. The maximum amount of Life Points a player has depends on player level, Energy, Attack Power, and Defense Power.

The Life Point formula is:

LP = level * 100 * X

+ atk * 5 * X

+ eng * 3 * X

+ def * 3 * X

Where X = 11, 8, or 7 depending on your atk/def ratio.

A ratio of less than 1.5 yeilds the most LP.

A ratio of greater than or equal to 4.0 yeilds the least LP.

(NOTE: if your def is greater than your atk then it is your def/atk ratio)
