Quick Tip: Always lolnexus or lolskill the other team in loading screen and look to see what the other ADC's rune page is. If he has no life steal punish them for it. If you have no life steal you better get some.
I'm a Plat I ADC for my team SM Gaming, if you have any questions or in need of tips just send me a message I'll be glad to help. Also I am a 2400 rated Feral Druid on WoW so if you need any advice with that also I'd be glad to help.
