A silly "what if" scenario. Let's say, for the sake of the argument, that Blizzard has released a new patch which, among things, gives access to an upgrade recipe for set items that is about as expensive as the other upgrade recipes. Let's also assume that they have not made any new sets or uniques and all new runewords are way too expensive for legit SP'ers to even dream of. When people have decried the percieved weakness of sets over uniques and runewords, the lack of such a recipe has been a common argument. Well, would it change our usage of sets all that much, if we could? As I see, it would not matter all that much. It certainly wouldn't disturb (the already horrible) item balance in any way. Following sets would probably be of interest upgraded. Arctic Gear: The Arctic Furs can actually spawn with 325% enchanced defense and with two set items worn it gets 3 defense points per character level as well. Imagine that upgraded to a Dusk Shroud it would have a respectable defense level. Still, it would really just be a toy for those wishing to be "different" as a Duress, Stone or Fortitude in a good Archon Plate would supply equal or superior defense while giving lots of good mods to go along with it. In case of Duress it would probably even be cheaper, runes wise. Death's Disguise: The sash upgraded once for those extra potion slots. The Gloves/Sash combination or just the Sash alone is already popular as twinking gear and with upgrades we might see characters wearing the belt in the endgame more often. Cleglaws Brace: While this set can work endgame, even as it is now, I'm sure people wouldn't mind some extra damage on the sword. Still, in expansion there are a lot of (better) sources of Deadly Strike and Crushing blow available and the fact that the shield will never be good at blocking is a serious deterrent. Iratha's Finery: The belt for that extra row of potions. Lovers of this set keeps mentioning it as potential end game gear, and we can always use some extra potion rows, just in case. Aldur's Watchtower: People have since it's conception moaned how an obvious melee-specific set has such a low-damage weapon. An upgrade could remedy this to an extent, though it will still not compare favourable to the nasty uniques and runewords out there, but it would make Aldur's just a wee bit more popular. Hwanin's Majesty: Upgrading the Bill could give it some longevity, though Colossus Voulges has huge strength requirements, so when your'e at it why not give the belt and the armor some loving too. The set would still not be all that hot when compared to the various unique elite polearms and the plethora of runewords that can be made in this weapon group. The mods on the assembled set just aren't that hot. Griswold's Legacy: Well, you could upgrade the armour for a potential 200 points of defense (if you are lucky with your roll that is) and the -requirements helps keep the strength req in the "acceptable" range. Orphan's Call. You could upgrade Whitstan's Guard if you felt it's block chance weren't already high enough, well it would mean less points in Dex needed which is always nice.
