I've gone for total damage and have full int with maxed passive int. I have 156 dmg 194 dps with 1750 health and 490 armor. I don't have the best gear, and those stats are with malison as my pet.

I've tried around 10 different skill builds, and currently I'm using 4/5 fireball 3/5 lightning 3/5 heal and 5/5 curse. I drop insane damage and am killing elite mobs in no time, but I have a lot less defensive ability not having gale for knockdown and dodge. There isn't a 'best' build, it depends how you play, and what's best for you. I am constantly changing my builds to see what I like. Your concern should be to reach level 20 before you start tinkering with stats.

Are you charging your heals? its pretty ineffective simply using the skill. Also try increasing your damage as it directly affects the power of your skills. And like energizeric said putting points in more than 4 skills is a waste.
