I don’t read the patch notes often enough, I realize that, so the following might not be new to you:

(Added 3/07) Avenger’s Shield: This ability will no longer jump to secondary targets which are under the effect of crowd-control spells that break on taking damage. i.e. Polymorph, Sap, etc.*

How epic is that?! I can’t tell you how often I broke CC with AS, just because the Mage would sheep before my cast. Not to mention that I had to be VERY careful when a group of mobs had a Sap in place. But oppress me no longer, I can cast to my willing!

Another (old, but good) patch note states the following:

Turn Undead (Rank 3): This spell has been reworked and has been renamed to “Turn Evil“. It will now work on Demons in addition to Undead. Turn Evil is subject to diminishing returns, and lasts 10 seconds in PvP.

Finally Paladins have a mean of getting rid of pesky troublemakers in Arenas.

Also, another interesting feature is related to JCers:

A new jewelcrafting recipe has been added to transform many green quality gems into a single random blue quality gem. This recipe is available from grandmaster jewelcrafting trainers.

Guess is time to stack up on those green gems!

*also works with Chain Lightning
