i shall try using the juggernaut to solo hardcore and triumph
It's easier than with Engi, trust. (I never got past W43 with Engi.), also try with Commander as 5th slot, even easier.

Yeah... That's true. Sounds weird, but Juggernaut can only deal with Swordmaster without Max Skill Tree because of his fortify on TP, which is extremely useful against stun and debuff fest.
