Slight dilemma.

So I recently hit lvl 25 and respecced to make my build more PvE elite friendly. But I have one more skill point in which I not know where to allocate.

My current build:
Fire (4/5) - no range increase, causes unwanted/unneccesary aggro
Ice (3/5) - no %20's, too situational/inconvenient
Time (5/5)
Life (2/5) - no HoTs or range increase, marginal difference at high levels, causes unwanted/unneccesary aggro
pINT (5/5)
pDMG (5/5)

I really don't think the clock explosion for time is practical. I noticed it doesn't make much of a difference or really finish off enemies that are snared, the range is lacking as well. Is the damage from the explosion viable or should I replace it with one of the %20 options from Ice? I've seen them increasing in popularity. Ultimately my goal is to deal as much damage as possible while providing team support.
