YusaMei No Alter ego didn't take  extra damage from 3 knight classes. Those deal normal damage to Alter ego, but only Alter ego deals less damage to them.

The only weakness they have is Berserker.

That's why Alter ego is perfectly fits in tank role.

Well, ruler is better but they can't do much damage while Alter ego can hit like tank to those rider, assassin, and caster.
