If I very clearly stated that I want someone that is actually going to play and not some mindless player that doesn't actually play, then telling someone not to use something to adjust to my preference isn't them playing the game, it's me telling them what to do which totally contradicts what I just said.
Uh, no, it's called communication and compromise. You're not telling, you're asking and asserting. Do you ever leave the house?
I already said if they use it I just don't play with them.
So... you waste your own time rolling characters and then quitting, instead of communicating beforehand and not only saving the trouble, but possibly convincing your partner to play the way you like if it's not that big of a deal to him.
