How does the game discourage you from flying?The Great Knights that normal lunatic stationed near the exit actually already discourage you from flying. it just dones't discourage you to reset and hope for a crit/DF on turn 1 over and over again, haha... just a couple outlaws and a Wyrmslayer unit should be enough to discourage you from going for a 2-turn flyskip
chapter 12 has a problem that Team Xander's Ai can be heavily manipulated by a flier. I honestly think that Xander could simply have a "only move is something is in range" AI to force you to use the DV. Peri and Laslow might be okay to leave as they were...
There is literally nothing to stop/discourage me from pairing Corrin to Subaki, and reaching the escape point by turn 2 by just going left.
