This is a typical trade-off of future growth potential for present power. Gaven would never make such a shortsighted decision unless absolutely necessary.
It's important to emphasize here that the rewards for Transcendent, Legendary, and Divine Attributes are sequentially unlocked. Even if Attribute Points reach the divine level initially, without first unlocking Transcendent rewards, not to mention divine reward options, even Legendary ones cannot be seen.
This is because the options that follow are not predefined but evolve based on the choices made earlier and a range of abilities one possesses.
Gaven's Strength is now in such a situation. After all, he is not a Warrior in the true sense in this lifetime and rarely uses his own Strength in battles.
