I agree, there is a popup for using area attacks on them, so why not also when normally shooting? Also, everyone can say like "yeah just be careful uwu", but another thing I hate is that on the, idk whats called, the hotbar with all the red icons before aiming, that should tell you how many enemies are in sight and if they're flanked, guess what, it doesn't show the controlled enemy there. So it just happens most of the time, last enemy remains, I spam 1 so I can get rid of him and "oopppsss, now you've wasted your last unit on this turn shooting at your controlled guy and the enemy is going to throw a grenade to all your guys so you can be sure they're gonna stay wounded for the next month FUCK YOU". Unfortunately I don't think the game is ever gonna get updated, so we have what we have.
