It's been a while since I've played, but the free heroic chars brought me back. I also like this time of the year as the Fabled mobs are coming and I enjoy hunting them.
I have made a heroic Shadowknight and have completed the Iksar Kukri series of quests and am now working on Greenmist. I have only the Chardok shard and Drusilla's mirror to complete it after which it's on to his epic. I am quite enjoying this (apart from the final Kukri timesink). Sometimes one needs time away from something to be able to come back eager and fresh to go!
