2H swordsman survivalist

I was planning a survivalist 2H swordsman with a touch of fire gems to boot. So a thought was to include the fire damage buffs from the bottom left corner but decided against it to gain some more armour instead...

I'd really like some input for this build and suggestions for eventual changes!

One thing I see is quite hard as marauder is to have an upkeep of mana, so how do you guys n gals solve the mana problem?

So I rethought this and removed all the sword damage orbs as they seem to be inefficient; and came up with this build with Resolute Technique and a bit more health and attack speed...

Seem like a nice change, but hey now I can use any two hander :)
