I think he wants it so that he can wear it from the start of the game.
Or even wear it as another class.
For example, I have a mandalorian sith warrior and a mandalorian trooper. Sure, both can use heavy armour, but they don't get access to that style from the start.
And I also have a mandalorian imperial agent, she can't even wear heavy armour, but thanks to the Mandalor the Uniter set I now have a decent mandalorian look on her anyway (sans helmet)
A decent, contemporary, adaptive mandalorian set would be nice. The Bounty event set is close, but not close enough. (plus, the helmet lacks voice modulation)
Fair enough, the armour is Iconic after all, a CM version would be nice.
