I have no problem with IE 2-4 shooting a squishy, as you can probably 2-3 shoot them back. My issue is when a tank gets 3-5 shot by an ADC with an IE. My proposal is that if you get the item IE, Last whisper is locked from purchase, making IE have a clear strength and weakness. Its strength being its crazy burst against squishy targets, and its weakness now being its much harder to take down a tank, or armor unit.

Raising the price doesn't really solve its issue, while lowering its AD could potentially work in the early game it still doesn't solve the late game problems.
TrulyBland2 votesIf a tank is getting 3-5 shot by an ADC with an IE the ADC is way way way up ahead. If you want to argue about an issue that can actually very accurately be expressed in numbers, it's best not to exaggerate or even just estimate. Actually use numbers.
Your suggestion would also harm Last Whisper more than Infinity Edge. Building Infinity Edge without Last Whisper will still amplify your damage against everything. Last Whisper only amplifies your damage against tanks. Even when calculating against an infinite amount of armor, you only amplify your damage vs tanks by 1.54 with a Last Whisper as opposed to an easily achievable multiplier of 2.5 with Infinity Edge (when considering the extra crit chance and the AD difference to Last Whisper).
All this would change is that Last Whisper would simply no longer be bought on ADCs at all and thus the meta would swing back to stacking armor instead of health as well as massively buffing tanks overall.
