I love an early last whisper . The problem with building it first vs tanks is that your lane opponent wont even have much healtharmor at that point and your impact vs squishier targets will be greatly reduced . I always build DB first . There is no reason to get a last whisper so early when you have an item that gives you true damage on no cooldown . After that , I will go last whisper zeal item LDRMortal reminder . Quinn is an assassin . As such , you don ' t want to completely itemize into tank killing if you want to have any assassination potential versus squishies . That being said , If you aren ' t getting what you want out of just the LDR , and you have space in your build get an IE so you can cut those tanks down AND pop those squishies .
