The only champs that build critical strike chance are ADC's, which are notoriously squishy and easy to take down, even as a full tank. Yes, carries may fill their health bar back up in two or three shots late game, but if you can't find a way yo do the measly 2k damage to a carry before they can lifesteal it back, chances are you're not going to win the game anyway. They need to be autoattacking at all times to survive. You force them to run, or cripple their damage output (Exhaust, Randiun's, Frozen Heart, Malphite Ground Pound, Blinds, Stuns, etc.) and suddenly the carry is no longer a threat and dies instantly.
