Double strike 2H axe marauder?

So i'm thinking about starting up a melee char to add some variety to my play. I want to do a double strike build with 2H axes (cause nobody does it as far as my google-fu has led me to believe).

I'm having trouble deciding between duelist and marauder as my starting class. I have a few items already lined up that I can use on him (6L 1600 evasion chest piece, armor/eva helm with decent stats, etc).

A rough build I threw together earlier (94 points):

Do I need to swap a few points around to get more endurance charges? Is it just silly to make a 2h build for endgame? Am I going to be stuck as IBchar78238583 if I want to do maps/lunaris 3/etc?
