Multiple attacks: Useful if first one is a kill?

[Endoperez]

Normal situation:
Unit chooses a target square into which it attacks. All of its melee attacks target units that started in that grid. Then the unit uses its weapons on units on that square. If a weapon (not unit) has multiple attacks, and the first kills an enemy, the second attack is wasted - weapons only target one enemy. If all enemies die from the square and the unit still has attacks, they are wasted - unis may target any enemies in their target square.

Quickness:
Quickness grans an extra action, which includes moving, targeting and attacking. Unit that has quickness and four attacks can kill three units from one square (1 attack wasted) and, thanks to quickness, then try to kill another three units in another square, again with four attacks.
