You shouldn't need to kite it at 99, just bring an evasion set and use magic barrier. Kill the campa near his spawn before you pop him and bring it to a safe area like the spot going towards Tunga.
I've actually been able to fight him inside the little nook behind where he spawns without any campas linking if you're too lazy to drag it far away.
Fighting him on BLU is great; you can build lights when you enter (I like to amber the treants), whisker cleave for the pop at chigoes, kill him, rinse, repeat. Don't need to worry about competition for Amun and such.
