your theory only works for short sighted managers. The managers with a deeper insight in the game know what you say is not true, and teams who actually are not stronger then others, but have such a manager will always end on top after a while.
Now to answer your simple question: why not just drop TIE and keep normal and CT in the play-offs: The reason why the new system was invented was to prevent teams to CT in the play-offs, sacrificing a lot of enthousiasms, which actually makes them a bird for the cat in the next round. This is not funny. A decent team who wants to win the title is kicked out because some weaker team decided they do not care about the title, but just want to get another round of income. Because of this BB has decided to come up with a solution, and I personally thing they did a GREAT job.
Here is the deal, they in fact dropped TIE, just like you asked, so there is only normal and CT in the play-offs. BUT, teams wanting to play CT, would normally loose a big chunk of their enthousiasm, leaving the defenseless againt their next opponent, so BB decided not to touch the enthousiasm, so a team can actually CT, and still have a fighting chance in the next round. Because it would be stupid to keep normal as it is, because then everyone would just CT, they decided to give a bonus to teams deciding they don't need CT to win...
It is as simple as that, the one follows the other in a logical order, and in fact the solution they ended up with is just BRILLIANT.
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
