I might consider something more hybrid if it wont break the bank
Or just go down one street

What works best for myself and groups?

low lvl = life and mana
mid + end game = int gear + ee charm + ee heal charm
works pretty well

stat vita to 30 minimum find max mana gear with Life per kill and Mana per kill if you can find a staff or dagger with 30+ ee and some max mana if you can with some mpk/lpk that way when you run out of mana you can melee and regen mana/life still without towning.

15+ u want INT as main stat on weapon/armor good adds are Crit strike Mind Numb Max mana Extra equip slots are always a plus. Ee on charms/heals plain ee heals work best dont pay for adds on heals they dont work in acc slot.

hybrid is a bit hard cuz u need this kind items
