It is a later game item on most champions you build it on. The only case i've seen rushing this item is kalista for the movement it gives her alongside the synergy with her rend. If you dont feel like you're dealing enough damage yet, it means you dont have enough damage items to make it worthwhile earlier.

To answer your question, you would never want this item if it's barely scratching the other two people. Chances are, if you're not dealing enough damage with the bolts, you're not dealing enough single target damage to warrant this. On AP on-hit teemo, I typically go Rabadons, Sorc shoes, Void Staff, Liandrys, THEN Hurricaine, then zhonyas. I would always rather win trades and get to the late game than be irrelevant at 30 mins.
