Dodging

Would you say it's fine to dodge a game if your ally banned your champion? And it's just because they don't like the champion/don't want you playing the champion. I can understand if it was an accident, a panic ban or u had just not seen the other person with that champ locked in. That's why i ask for a reason whenever it happens to someone in my game. But if you're just doing it out of spite, I can't really play with you as I've lost all trust in you. It rarely happens, but it happened to another person in my group just now and the banner wouldn't respond (he/she was the first ban and i questioned them as soon as they banned the champ and waited until it was my turn to lock in a champ to play but they never responded. The other guys were fine with my logic but I wanna know some more opinions on the matter.)
