I feel like a mother duckling protecting her young.

Alright so I have mained Top Shen and Jungle (Warwick, Sej) for a long time. Not because I cannot lane but because I need to protect my teammates. I will play Yorick top and decimate my opponent only to have the rest of the map be on fire. I am very skilled at the new Warwick (my last game I made a mistake of trying AP Jung warwick don't do that) and gang EVERY lane starting at level 2. I often get first blood or help a teammate get it. I go full movement speed runes and mysteries and run around the map like a Cheetah on cocaine. But this is getting super boring. I will likely win the game if I play WW but it gets repetitive. The same goes for Sej and Shen, I babysit people and make sure they don't get killed or caught.

What should I do? I want to rank up but I've been playing the same champions again and again so much it's just sapping the fun out of the game.

I recently have been playing Sion Sup with a fair degree of success but again every other lane lights up in flames because mother duckling (me) is not there protecting everyone.
