so armor tech is the way to go ?????
If you have to choose between the two, yes it is.
I had armstech and armortech ( on 2 differents characters ), I make more money with armortech selling augments, fully moddable orange sets, bracers and belt and epic lvl 11 to 50 armors. With armstech you sell augments, few people buy orange weapon and even less by epic weapon ( for leveling ).
That is my experience.
Note : I play on a French server, maybe the market trends are different on US server.
