Fighting a Goliath is fun. He fits the poster-child of the monster team well. All pre-game buffs work well for him, making him very customizable for your playstyle.
He is able to gain good distance on the hunters, but still can be tracked and caught in the Dome - making it feel you always had a chance to engage him and chasing him direct and cutting him off are both legit paths.
All his abilities have appeal. There is no ability that is underused in my opinion. Leap and Charge do damage but can also be used as extra distance gain for escape. Firebreath is iconic, does great damage, and helps find tricky cloaked characters. I personally use Rock throw the least, but its a great ranged attack to help deal with Hunters keeping their distance, or as a follow up on a Charge/ Leap.
His Health is fantastic. Sure its annoying to have a Goliath on 1 bar of health escape, Evolve, and regain a decent chunk of new health, but its also engaging. Its nice to have that brute you put the hurt on earlier come back with a want for blood and revenge.
