I played E/N up until recently and I loved it. I went fire, blood, and energy. I simply used a bunch of AoE and life stealing skills to dish out massive damage and keep myself alive. Healers loved me and it soloed well. Ended up with 12 fire, 12 blood, and 9 energy with all minor runes and it worked out great. A few days ago I switched to monk secondary to give it a shot and I love that too. Don't do as much damage and can't heal myself as well (my best single tartget heal ATM can't be used on me: 'heal other'), but it sure is easy to find a group spamming "12 fire/12 healing lfg".

I predict I'll probably be switching back and forth a good bit between the two based on mood.
