Just do this; Melee carry against squishy teams, on-Hit against tanky teams. Profit. It's a bit more detailed than that, like if I have a vayne on my team I may go melee carry to assassinate the backline since I won't need to worry about tanks, but for the most part, that's my guideline.

It's true it's usually better to focus damage threats, but if they have a lot of dive tanks, and you're playing someone who can kill them as fast as Yi, then you can often kill the tanks faster than even a bruiser would die to the enemy adc, giving a default numbers advantage.
