Short answer, no.
Long answer, depends. Early game, Precision or Speed are pretty damn good for single point investments. Towards the end of the game (circa level 19+ or so), you start to run out of DPS talents. At this point, you can invest the other 3-5 points into the tree to maximize a sustained you're already using or get utility talents. I personally fully upgraded Speed at the end of the game and I don't regret it.
