I am putting together my first warforged. He currently is adamantine 2/1 Fighter/Rogue that likes to fight wit Two Handed Weapions and had the following creditials with some decent gear. AC 22(20 +2 Docent) STR 20 (18 +2 Ogre Power) Dex 14 Con 14 Int 14 Wis 7 ( 6+1) and Ch 6. I took the dodge feat., and healers friend. I am about ready to level up.
My HP so far is 57


What I want to know what can I do to get a unbuffed AC that will be manageable while using Two Handed Weapons ( I love Great Axes and causing damage from glancing blows. What is a level appropriate AC for a warforged that is in the 4,5,6 levels?

I was thinking for the next level to take another level of Rogue eventhough I think the evasion feat is negated by the Adamantine right?
