New ADC

Caster ADCS:

Whatever happens, don't play Ezreal atm. He's weak. If you want a caster ADC who does build a fair bit of crit, I suggest picking up. He has insane damage on his Q, good attack speed for trading in lane from passive, Inbuilt grievous wounds which works very well against heal and soraka/sona, and a good teamfight ult, which while not at the same teamwiping level as MF ult, is still insanely strong when used properly

If you enjoy teamwiping like MF does, Twitch does similarly. He is more autoattack than caster though.
