you don't need to defend against everyone who has lower speed – it's enough to make everyone wait! the one who was demoralized always goes first in the round of waits
That's clear.
Let me give an example. Group Vaska attacks group demon. Freezes. The demon, according to our assumptions, makes a wait. We also have an angel in our army, who waited, and 2 level 1 gnolls. If we make the gnolls wait, and then attack, the demon, in theory, will still go. And if we make them defend, the demon, according to our assumptions, should also skip. Then the angel will attack him, and the demon won't go in that round.
And by the way, with "blind," the surrender is twice as weak. And with "freeze," will you hit him twice as weak? And he hits you as usual?..
