Ark Best Fighting Dino: The Yutyrannus in Ark Survival Evolved
In my opinion, the best fighting dino in Ark Survival Evolved is the Yutyrannus, if you think about dinos fighting in a team. The feathery yuty gives a 25% boost to damage to its buffed tribe's dinos while those dinos will take 20% less damage. The yuty can also scare away other dinos, and give them a de-buff.
