How to be more engaged with your team when you don't play "the most meta" of champions?

I am a top main. I have been since I started playing this game, it's a fun position. I notice a lot of people play a certain few champions in the games I play in. It becomes pretty routine and I am learning how to counter most the top meta champions pretty well. My problem is that, while I see why these champs are played, they are boring to me. I played Darius, Wukong and Fiora....None of them really fit my play style. So when I pick something that is fun to me, for instance - Kennen, my team becomes less willing to help me out. There are almost always comments directed at me and actions to work against a team based play where I am constantly ks'ed by your hyper-carry champions like Zed or Akali, who then take my farm top without me even asking for their help. Sure, I get the assist and it doesn't really matter but when I am chasing a dude down river with my ult and you come up and last hit him, it's annoying.

I can win my lane even, try to engage on a team fight and have them walk away. Sometimes I make it out sometimes not, then I ask them why they do it and they say stuff like: "You played Galio top" Or "Cause Kennen sucks." It's really depressing seeing a roster of champions but knowing that your team will be more willing to help out a Yasuo top before they'd help a Vladimir top. It makes me angry when Riot is pushing for this team-based game style but then you have to stroke everyone's ego's. How am I supposed to get my team to engage with me more or be more willing to play beside me when they constantly create this meta of "only these champs work."

So I suppose my question is: How do I play a game that is ever more developing a need for strategic team work when my team constantly doubts a champion I've selected?
