I used to play League every day. I never really delved much into ranked, though with the about 15 games I actually played in ranked, I reached Silver 3 or 4. I never put much effort into it, but my room mate, who is actually worse at the game than I, reached gold about a month after I quit playing.
The reason I quit playing was because Super Smash Bros. for the 3DS was released. Lmao I've been glued to that since. I'm trying to get back into League now, though. Learning the new jungle (my main role) is kind of tough and I'm not even sure where to start with builds and paths. I hear from some people that jungle items shouldn't be completed and are a waste of time and money, while others say completing the items first is essential.
