Will this be solo exp, or duo'ing, or in a group? I think I level Harrington (ranger) in NC at that level, doing the elites in the little side tunnel by the WoS zone line. Should be even easier for you, as a necro or druid, since I was doing it by root and shoot. There is plenty of room to kite just outside that tunnel to the zone line, and as an added bonus there is the zone line right there to run to if you get into trouble. I never did it, but I hear Tipt was good at that level, especially for a Necro (FD). What about some of the isles in The Buried Sea. A few of them have ALOT of animals on them, and a few have undead. If you are grouping, how about doing the DoN progression, I think eventually you will get missions that is very good experience for a level 65. I think same goes for the DoDh missions (especially the 69.1 spell mission, which is great for kiting classes). Lastly, I think, if grouping, the instanced zones for getting your Anguish signets is good at that level. These are just suggestions, based upon the places I keep hearing about or were nice for me.
