definitely not a very popular build from me:
an aggro-less support mage:

skills:
3/5 ice (no DoT, no ice patch on kill)
3/5 lightning (no stun, no splash on kill)
4/5 fireball (no DoT)
2/5 gale (only speed)
5/5 timeshift
3/5 heal (no heals over time, no mana over time)

passives:
5/5 str int dex crit

:P
