I think that each set of armour should have a number of slots in which you can place enchantments (making them untradeable forever). So for example, a set of bronze armour would have one slot, whereas a set of rune armour would have 3. There would be a wide and varied amount of enchantments one could choose such as +3 strength, +10 hitpoints (when fully healed), or even non combat enchantments such as +2 woodcutting, or what not. This way there would be a whole other equation to combat in runescape as you would have to choose the best combination of enchantments to fully utilize the advantage they give. This would personalize each set of armour and it would make you need to look at combat in a different way. Going fishing? You don't want to wear your +4 defence rune armour then. Going clan wars? Then do you value strength over defence and attack? Or the other way round? Maybe the amount of slots you get should be dependent on your defence level? That way there is actually a reason to get higher defence (stopping defence being the least liked of the three skills, a lot of people max out defence at 70 or 75, with this update people would want 99 defence for its advantages instead of just maxing it for the sake of it) without bringing in overpowered armour that noone can hit through.
