im not personally a fan comparring him to spartacus from history its kinda dissappointing im hoping he gets a saber version that has a lot more character of him as a person and show more people who dont know his sorce what he is all about and why he hates oppressors so much.
In terms of base game damage, yes, in a way, he is has the lowest damage not only in the berserker class but of any class (not counting his damage modifiers and ME buffing his Buster damage by 10 percent) but in a lore sense, he is one of the stronger berserkers surpassing Eric Bloodaxe, Kiyohime, Caligula, Phantom (berserker), Fran and many many more berserkers.
