Suggestion for Nidalee's Spears
So, we know that Riot is working on Nidalee's kit a little bit, but I wanted to offer this suggestion. We already know that the current identity of Nidalee's spears are changing, so I'll keep this brief by skipping justification for the change.
So instead of increasing the total damage by a flat percentage (up to 250% at the moment), I would suggest that the spear gains increasing bonus damage based on current health, up to 25% of current HP. The catch, though, is that I would suggest this bonus current health damage be applied after the initial damage.
That subtle change makes a big difference. Basically, if the base damage (which I wouldn't change) doesn't kill you, the bonus damage mathematically cannot kill you either. Now, a spear can still kill you, but it would have to go from the initial 230+65% AP damage, which is only slightly lower than the other long range champions. Plus, it will still provide a reward for singling out specific targets during a seige (particularly high health ones).
