About classes, we will get significiant rewamp of all classes in HD. Thing is in closed beta currently, so read dev diaries and wait for open beta to see and learn new changes. If you havent learned the class now, no big need learn it for a month only to relearn it afterwards. If you still want to, there is a class subforum, where stuff like you asked for is discussed in great details, with links to guides and all. Just that it all will be obsolete in a month.
Thank you, Turbine, for listening and giving us an opt-out of FE! Good work!
