So I simply didn't have a good enough armouring mod to make it competitive with the other armour I was wearing.

I don't think I'm fully understanding how this works, and would be rather grateful to have it explained to me. I picked up some fully mod-able armour as a quest reward. All open slots, and an armour score of 25. How exactly does the level scaling for modding armours work? Even when I stuck mods in it the 'armour rating' was as high as the armour I was wearing, but the armour score didn't go up so it was either wear the 25 armour or the 200-or-so armour I had on at the time. Am I missing something? It just seems like fully modable gear is there purely for stat boosts, or does the armour score go up as well and I'm missing something? Cheers!
