I don't understand the comparison between the predictions of the tactics and rock/paper/scissors, simply because you will now just play rock if you are very sure your opponent plays scissors (and in some desperate cover your head and brace the impact situations). I wonder if people missed the announcement that you don't HAVE to make predictions, you have the option to do so.
I agree this is not pure blind guess like in rock/paper/scissors.
Nevertheless it drives the game it this direction. I man you will deliberately play your least favourite tactics in games that you might loose, to try to mislead you opponents. This element is still present in the game, but too a lesser extent.
It's clear for me that the guessing is not manadatory, but the point is that if you guess correctly, you get an advantage and if you guess was wrong you will have a small penalty. Facing a stronger opponent, why wouldn't I take more risks anyway. For the underdog this is a no brainer. And for the favourite this is an extra matter of concerns. This will have an impacy in sinle elimination game like PO and tournament. So the side effects would be much worse than what this new option is supposed to cure.
I'm really concerned that the guessing with tactics plus the new guessing option would overshadow strategy and planning.
And will lead to a sort of meta guessing game.
The LI dominance is not good, put peoples are just pinpointing the weakness of other offensive tactics and weakness with Z2-3 or Inside box.
For me it's a clear case were the fix is worse than the problem.
