The answer that was given is far to vague for what I desire.
The question was Do certain weapons do more damage to shields/barriers/armour in Mass Effect 3. I have discovered a potentionally similar question that i will address. I am looking for combinations that work in Multiplayer as well, not just Single Player. There has to be a weapon/mod or combination of biotics/weapons or combination of biotics someone has discovered that is aggressively devastating to units with armor.
I find myself having no trouble with damaging units with shields or barriers but it seems taking out targets with a bar of Armor is a grueling and sometime deadly process (for me).
