So here's the thing I have been playing Jungle since Season 3 and 4. But lately, I just can't seem to get wins or do the things I would like to as much. I can't seem to carry anymore from the jungle as it's shifted. Recently I played a day of mostly mids and only lost one game out of like seven. If you check my match history most the games on Leblanc I had over 20 kills and fully stacked Mejais. The farm was off just since I don't play mid that often generally. I am wondering if in Silver if I should just go mid and push my way into higher elo. Or maybe if I should just keep trying in Jg and just try to make the best of the situation.
