Very Casual gamer looking for Silver ranked

I have a full time job but I'd like to get in on a ranked team. Honestly I'm tired of constantly playing with AFKs so I figured ranked team would be better. I can only play a couple games a day and most weekends I'm good for a while, don't have Skype or any teamspeak, like I said, I'm pretty casual. I just want to get on a team that may need me as a fill in from time to time, I don't mind being a sub when people can't make it.

So anyway, about me.. I can top, mid, and support. My tops are darius/yorick, mid is veigar, and support is sona/yorick. Yea, I've played other chars but these are my solids. I'd rather stick with these and give you my best. I've been as high as silver 1 but after a string of afks and "I'm x lane or I'm feeding", I'm pretty much dropped to silver 5. Look me up, enzodabaker. I know this is prob a long shot but if anyone wants to give it a shot, just hit me up. Let me know in advance so I know you're not a random friend request that will ask me to click a link for free rp ;)
