The Mandalorian(Beskar Armor) - Useless character.

So I took this miracle. Dressed at 12 tir. And I don’t understand. What is the point of it. He does not give out a lot of damage. Although it requires a lot of resources.

Tell me, is anyone impressed with it? Does it make sense to wear him at 13 tir?

Or is he the most useless of all the characters we get through a complex event.
