How hard do you dump your dump stats?

I've been making some builds and wondering how unbalanced my stats should be in creation... up to 18 points (pre modifiers), one statpoint costs 1 point and above it costs 2, so I have been leaning towards quite balanced setups, where I don't buy many of the 2 point increases at all and then also have all stats at 16-18. Just not sure if that's the way to go, or if I should actually dump sole stats harder (e.g. Int or Ego) to get a bigger + in my main stat(s)
