I think it would great if one could improve a weaker armor, so that we who like the look of a specific armor can use that, instead of another more advanced (and diffrent armor)
these upgrades would of course be as costly as gettning a new diffrent armor.
Naturually this option would reduce the tactical advange of those of us who can identify armors purely by its looks (and therby know how weak/powerfull ones foes/teamates are) making battles more challenging, and cause less discrimination vs less experience players.
