Recently, first time in my player career, I have reached level 11th. I choose to have an apprentice. My elven Mage was teaching Dwarven artificer how to be brave/useful. Unfortunately I had a trouble distributing spotlight among my characters and Dwarven girl is often forgotten. As I know my Elven character better and he is more powerful I tend to use him in battles. I never had a chance to step into second character shoes.
I had an idea how to fix this. I talked with my GM about possibility of retiring my level 11th character and only playing new one. He declined, as I have suspected, replying that it is impossible to revert my decision. That made me really upset because I wanted to play and now I will remove myself from the game completely as I don’t want my character to be forgotten and feel uncomfortable to play both.
My question is. How would you solve such situation from both GM and Player perspective. I’m also DM so it will help me decide in future. I know that each party has to decide themselves but what would you do?
