2H Melee Internal Trauma Build Help

I wanted to build a 2H Melee Internal Trauma based character.

But I just can’t decide which 2nd class I should choose beside the obvious Soldier.

I planned something for this on the soldier side: (Can’t post links)
Cadence: max/max/max
Fighting Spirit: max
Zolhans Technique: max
War Cry: min 1
Olerons Rage: max
Field Command: max/max
Decorating Soldier / Miltary Conditioning: min 1 both

Either nightblade for some additional bleeding damage and more important the pneumatic burst heal or shaman with 2h line (feral hunger) and overall survivabilty with Mogdrogens Pact and Briathorn

Also I ask you for some opinions on the old blade arc vs forcewave question, which would work better on this build? (Both have some Internal Trauma)

And as the movement Speed escape/initiate spell: should I choose blitz or shadowstrike(when go nightblade)?

Thanks for any help in advance.
