Mmmm...I see your point, but that's kind of option 2, where I don't agree to the TIE-TIE.
But, let's say that I counter the TIE-TIE with a normal-TIE, like you said. Why would team Y agree to this? He's throwing away his advantage. Besides, if I were team Y, I would ask myself:
"Why would he want to play normal when I'm the stronger team and I am the clear favorite for this game? He knows something I don't know. I don't want to lose this one, screw it, I'm playing normal. Better safe than sorry."
How did those games when you played TIE while your opponent played normal turn out? Did you win all of them? Well, you might have, you have a very solid team
