Suggestion: Taunting
I was in the loading screen today for FE and I read about upgrading your units les they become dragon fodder. And then I went thinking, (quite a painfull experience,) what if I want dragon fodder? How could this work? The most obvious method would be that a unit could get a "taunt" trait that lets him use the "taunt" abillity. With this taunt abillity the unit can force another unit to only attack the taunter. Of course this could be hard to encode. So my other suggestion could be that the taunted unit gets a minus in precision and the taunter gets an equal minus in dodge to compensate.
This abillity could have two flavors:
1. A slave master drives his minions into the ranks of the enemy, breaking the minions lines, but causing great chaos in the enemies ranks.
2. A company of noble knights challenges the evil minions of the dark lord. Hoping to avoid casualties among the peasant archers.
