Need motivation to play ranked! :(
So i have been playing league for a couple years now and most of that time has been spent in normal's (1,500 wins). And i just need some sort of motivation to play ranked. I have done some of it in the past got placed in sliver 2 and i felt like that i was a'lot better then that and some of my friends who been playing this game a'lot shorter then me have been placed higher. in most of my normal games i have either carried or came close to it and i don't lose my lane a'lot. My biggest fear is that i will get place low like sliver and not have the determination to get myself higher. So what do you guys think i should do?
