Re-maining from Druid to Necro, maybe.

Having played a necro to 60 I'd say it seems to match your wishes pretty well. Being an extremely proficient soloer combined with FD to go afk forever at a moments notice really is fantastic. Be aware that at 60 the (torpor) shaman and enchanter pull away in terms of solo powers but the necro is still pretty sweet.

Edit: you're going to want jboots and pre nerf cos. Other than that gear won't play a huge factor in your early life. 55hp rings and whatever else you can shop for 2-3k is ample.
