I sense a great amount of intolerance here towards changing the script, and that seems to be the real reason for a lot of the arguing, but at the end of the day, it is no use moaning about if I am gonna do it or if I should do it, as I am doing.
It's your mod, you could replace all the characters with chickens if you wanted, why would we care about that? You didn't ask our damn permission, you asked if we though Cait Sith was as worthless as you do. Where does disagreement with this statement translate to us just being defensive of the game?
What isn't in question here is that Cait has a very poor story, and that for me personally, and others, he broke the suspension of disbelief.
THAT's why people are arguing with you. You asked what people thought of Cait Sith, a couple people agreed with you, others did not. You rebutted the thoughts of those that disagreed with you. In and of itself that's fine - its what we do here - its your sardonic demeanor that causes people to straight-up oppose your position.
You keep saying we're missing something so simple. THIS is simple and you have not grasped it because you have not attempted to. Nor will you, I imagine.
