When you are face to face with an opponent not know if you activate the armor or not. Because if it is in the armor are slower and can not fully exploit the enhanced module aims (lv 3 provides more mobility when aiming) but I have more protection if you do not focus on the briastplate I have more movement but I do not have the same protection that I have with the armor. it is true that if I move to the left and right sided opponent will have more difficulty in looking at me but I happen to avolte even aim correctly, and I'll kill me booooooooo??

For me it depends on the situation. If i'm meleing, cant out run the oncoming grenade or pretty sure i'm going to die then I switch to armor mode, but any other time i just use the extra seconds that i'm shooting to recharge my energy.
