Because it was against my character. I try to reason with him by offering to change my background or deity, but he said it wasn't easy. It was either go with his plan or rip my character so I rip my character sheet and left the group.
Thank you for your replies, I'll try to use this a future reference incase I run into something similar in the future.
I hope future players and DMs look into this thread if they also find themselves in a similar situation.
I can't tell you how much your replies mean to me.
I tried to explain it. There are players who just want to roll, relax, and enjoy the story by the DM. I think the last thing he wants to hear is how boring his background or he is not roleplaying enough. I been playing D&D since 2005 and I never experience such behavior in my entire life.
1. What's your thought about a player telling other player how to play their character?2. As a DM, how would you resolve this issue?3. Is having a character with a boring background or playing him boring is a legitimate to tell him how to play his character? If you wonder if this happen to me...
