It looks like some good things coming with Rise Of Isengard http://www.lotro.com/gameinfo/devdiaries/1350-rise-of-isengard-developer-diary-itemization
Summary: Rise of Isengard will…
…provide more rewards, and those rewards should feel more impactful.
…make yellow items more potent, but not more potent than purple ones.
…provide solo players with an opportunity to acquire four of their six piece class set.
…provide brand new chests in classic instances, scaling raids and skirmish raids that will drop desirable loot.
…add a new stat called Finesse that doesn’t function like a content gating stat like Radiance did once upon a time.
