Hitting a snag

[Natewest1987]

Looking for advice on my 16 necro and 14 Druid. Really not sure what to do with them right now. Necro is supposed to be easy soloing, but I still feel like I’m always staring at the spell book. And it takes half my mana bar to kill anything. My Druid? I don’t even know where to start. Shitty heals. Not sure if I’m supposed to LFG as a healer or DPS. Tried charming things... it wasn’t very successful. What am I missing here ? Not sure where to hunt, solo or group... etc.
