100% imprint it and it is a beast of a dino to protect your base as the new nerf made the gigaz hp go down and so it enrages quicker but when imprinted it has more hp and damage even 50% imprint will do the job
WHEN TAMED! On a pvp server mostly make sure 100% of the time he/she is in a separate cage completely away from all other Dino's!! This is because after a certain amount of dmg done to the giga he will begin to "rage" he will turn on you even after all the happy memories you've had. Also even attacking all his Dino friends! :( so be sure to lock up this beast of a Dino!
