ADC
Attack damage carry is a part of the double team in bot lane. The idea is that the ADC will stack a lot of attack damage and wreck the enemies in the late game by last hitting the creep (though this should be done in all lanes, at lower levels the ADC gets scolded for low creep score in League of Legends).
Caitlyn
Price: 880 RP – 4800 IP
Caitlyn is one of the easier ADC’s to use in League of Legends as she has a wicked long auto attack range, making it easier to stay at a distance and not over extend. She is good against Vayne, Corki, Twitch, and Graves. She is bad against Sivir, Varus, Jinx, and Tristana.
Passive – Auto attacks grant a stack of ‘Headshot’ and at enough stacks her next auto attack will do bonus damage.
Q – Long ranged skill shot that will pass through enemies, dealing progressively less damage.
W – She places a trap which will root enemies who stand on it.
E – She fires a net which shoots her backwards and slows any enemy the net hits.
R – Caitlyn locks on to an enemy champion, from a unfairly long distance, and fires a projectile that will damage the first champion it hits.

Sivir
Price: 260 RP – 450 IP
Sivir is also a very easy ADC to play in League of Legends because one of the biggest parts of this role, last hitting, is made easier with her Ricochet ability. She is good against Caitlyn, Jinx, Blitzcrank, and Graves. She is bad against Vayne, Twitch, Kog’Maw, and Tristana.
Passive – Hitting enemies with auto attacks grants bonus movement speed for a short duration.
Q – A moderate damage skill shot that will pass through enemies twice, once going forward and then again returning.
W – Her auto attacks will bounce among enemies causing increased damage
E – She will shield her self from the next ability based attack and gain mana for it.
R – Passive: Sivir gains attack speed when using Ricochet. Active: Sivir increases her movement speed and that of her allies around her.
