Norscan Giant

Norscan Giant is a Norsca melee monster unit introduced in Total War: Warhammer. He follows those who wage war for the Dark Gods – their killing fields are his feeding grounds.

Description
Giants are monstrous humanoids with a prodigious appetite for violence. They are single-minded engines of destruction most often encountered in the far north of the world, being fond of the cold, rocky climes. Many find themselves lumbering alongside the warring Northman tribes, either for their fill of fresh meat and strong alcohol, or simply for the promise of slaughter and battle. Many Giants of the north are instinctively drawn to the raiding men who seek to bear the favour of the Dark Gods – perhaps because the corpses are always thick on the ground in the company of such individuals. Smashing into enemy ranks to kill and feed, they have no real concept of obeying orders but, rather importantly, do have the intelligence to recognise friend from foe.

Strategy
Use a Mammoth instead, giants need their own recruitment building at tier V. Mammoths are already available at tier IV. Mammoths have a better AoE attack too, able to shred enemy formation with ease.

In defence of the Giant, they are a more well rounded armour-piercing unit. While they have the anti-infantry tag, they do not have an actual bonus vs. infantry, which mammoths do in spades. The Giant has almost double the melee attack because they do not have a bonus vs. X to boost themselves. They also have a decent amount more armour-piercing. Still, the mammoth is generally better because of their superior speed and large bonus vs. infantry.
