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 :)
tie vs normal was quite normal on nt level, where ct are more common(a and neckbreaking) then at least the league i play.
But when you have clearly the better team and suggest a Tie vs Tie, such a onesided deal would be more a joke for the one who get him and i believe in such cases they got broken more often. But when you say i am afraid of your ct, so that i wouldn't play tie against you but the enthusiam would be nice for future games so i suggest you a normal vs Tie ... Then i got an enthusiam boost, and you have a little chanche and can still crunch another opponent.
