In this forum the MP games are taken fairly seriously. The "try something, it goes bad, drop out" tendencies are considered to be all worked out before joining a serious MP game. On some forums they are even more serious about it and some its less but here its considered to be a commitment when you agree to play. Keep in mind that its not just you being affected. An AI player is a whole different factor than a human one. When you go AI, the entire game is changed. A good player will completely redo their strategy. Many of the serious players will consider it to be a rude thing to have done to their game.
A more honorable option is to find a substitute. No matter how pissed you are, and how crappy you think your situation is, a sub can often be arranged. Brand new players will (or should) enjoy a chance to learn how to do MP turns, to see major armies doing battle, to see how an MP game looks in mid-game or late-game. Even if its just to die the honorable death, that can be instructive. I understand why YOU might not want to but they wont have that connection to the god you made and possibly lost. Give them a chance to slip into your spot, please.
