I Am Legitimately Considering Playing ADC Because...
SO many ADC's don't understand what
does or how strong it is.
Up against a Draven with Warlords? Get this early.
Up against a Soraka? Get this early.
Even if it's not someone who heals alot, you can most likely still outtrade that person just because of the grevious wounds that is insanely strong.
No, I'm not saying you need to buy this first item. But get it early so that once teamfights start happening you'll have this ready to go. It will win you SO many teamfights, especially considering how strong redemption currently is.
