The difference of communicating and just telling your team to suck it.
Communicating:
You: "I want to play this champion with that playstyle. Its really different to how the role should be played and you all have to play around me, are you ok with that?" Teammates: "Sounds dangerous, we would rather play traditional and safe." You: "It works, but I understand that you would feel unconfortable, especially since, like I said, you all would have to adapt to me... You sure you dont want to risk it, I promise it works." Teammates: "Look, Some of us are in promo games, we would really like a safe game..." You: "Ok, its 4 against one, I will play a more tradintional way."
Telling your team to suck it: You: "I want to play this champion with that playstyle. Its really different to how the role should be played and you all have to play around me, deal with it" Team: "Please dont, we...." You: "INSTALOCKING, COMMUNICATION FUCK YEAH!!!!!"
