Never intended to put you in shadow. I was just wondering if it were possible to update the ME3 armor system by using the light/ medium/ heavy. After all, why does biotic shepard wear an bulky armor?
Because he doesn't like getting killed?
Don't class armor. Even D&d loosened these restrictions. Have armor types have benefits in themselves not tied to class abilities that give you reasons to take any of the levels. Infiltrator in heavy sure go for it. You give up mobility for being a tank but it shouldn't make you less invisible it reduce the duration of your powers.
