If your playing against a Healer in bot lane

Lol I tell my ADC that and they buy it when it's too late.

+ loses trades to either or and the enemy is still getting healed, even if less efficiently. If smart the support will hold onto the heal until the effect is gone if it isn't an all in.

At higher elos, supports roam more meaning the ADC is less likely to make use of the item.

Unless you are playing against , rushing an is a mistake and you are bad at LOL.

They never will... Next option burst them both with brand! mehehehehehehe
