DM Nerfs My Character, Then Only Makes Her Useful Once I Change Classes

Honestly, it is a happy ending. It’s easy to recognize when you aren’t having fun and try to figure out a way to make it better. The DM being stubborn and refusing to see how the changes to the games system would kill any enjoyment for playing a caster is wild. Who would enjoy taking a turn just to fail repeatedly? DND is about player agency and having a good time, the DM should be fudging rolls in the players favor not the other way around. I know the game that she will DM will already...
