I was playing Mass Effect 3 online yesterday. I came across a player whose tier had Geth Engineer. The Geth Engineer was providing a great defensive support to the team. I was unable to beat that Geth Engineer as hard as tried. Finally I got defeated. Impressed by its performance, I got a Geth Engineer in my tier too. I had enough gold to upgrade him to a high level. But when I used him in my team, he seemed so useless as compared to the other one I had faced earlier. Now I donít have cash to get another replacement and upgrade that player. Can someone tell me how I should use the Geth Engineer properly so that he becomes powerful? I want to what should be the best strategy that will exploit every power and ability of the Geth Engineer to fullest and help me achieve success?
