Well, there were a bunch of runic changes in February 2008, and there's more changes for crafting coming with Stygian Abyss.
As for resists on weapons....
Still get them, but I don't understand where people think having them is odd.
If you look at gaming in general, the idea of resists/armor attributes on weapons goes back a THIRD OF A CENTURY now, to D&D's Defender (plusses could be used for defense to improve armor class) & Frost Brand (fire damage effectively reduced to 1/2 or less when wielding weapon from combination of improved saving throw and damage reduction) Swords.
For that matter, it goes back hundreds of years in legend and literature. Note that Excalibur (or its scabbard) had anti-damage or defensive properties, as did several other weapons, like Durendal.
Granted, the property should be RARER than it currently is in game, but it's not as nonsensical as you think.
