Necros soloing 1-50?

[Healthcare]

Is it possible for necros to solo 1-50? No grouping whatsoever mind you. If so, does anyone have a "guide" of where to go at what lvl ranges or so? I've been googling around a bit but can't find anything for classic zones and the like. Been feeling really anti-social lately and not wanting to play something that needs to group all the time so any help would be appreciated.
