Utility of the argentavis:

Jack of all trades: decent stat distribution, good attack, utility, and stamina.

Weight/long distance travel: high stamina, high stamina efficiency, and high weight stat

Material carrying: weight reduction on many materials like metal

Taming: has good attack to clear area and good health in case of getting assaulted by carnivores. Has weight to carry traps. Can also fly away in case of danger.

Regen: heals astoundingly fast after eating a corpse

Carrying dinos: able to grab mid-sized Dino’s like ankys and parasaurs.

Disadvantage:

Speed: much slower than other flyers like pteranodons

Difficulty to tame: found in dangerous areas (redwoods, snow, mountains, carno island)

Saddle: unlocked at a fairly high level of 62, and requires a lot of chitin/keratin
