Question about "Breaking the Rules"

Hi everyone, I was in a game of normals today and I wanted to try something new. Well, it isnt exactly new cause of a streamer or two, but I wanted to go bottom lane Rengar. I clearly told my team that I was infact, not support, and going bottom Rengar. The Vayne in my lane complained the whole time, asked everyone to report me, etc. I was wondering about the rules in general and using this situation. Trying "new meta" things is obviously going to make some people mad. but if you clearly tell your team, try it in normals, and keep a positive attitude. Can they report you for "trying something new"? Thanks for any input!
