Fiddlesticks jungle vs Karthus jungle who outfarmed the crap out of me

Feels like he knows how to steal all ur camps quickly, while having his team help and coordinate for him :P. meanie weenie. I was annoyed and typing about needing some kind of vision around mid or my job and jungle are both done, but then I know I can't play while typing so I mentioned i'd mute chat and go back to using just pings so I can focus. Game = hard. This is only silver. Good thing im not master. only gets harder on up :). I hit Silver 1 on this game, so maybe I can squeeze back into gold before year end. If luck holds up. I looked up his op.gg and he is a main shen top, with no listing on karthus experience. He apparently pilots him well. Some people good at playing wide pool of champs generally, i'm figuring if I played random champs loosely especially in ranked, i'd feed, when I try it in normals my lack of knowledge shows. This is ranked game.
