Transitioning from Multiple roles
So, I am long time LoL player starting since midway beta. I have played mostly bot lane for roughly 80-90% of all the games i ever played and enjoy playing adc or support. Yet lately I have obtain an interest in playing other roles including my long-time fear of jungling with all it's stereotypical blames and what-not. My question is simple to the community: What are the biggest keys to being a decent player on each respective role of top, mid and jungle?
