It would be even nicer if user can edit things (easily) such as:
Percentage/amount of hitpoints the dead unit's animation has
percentage/amount of hp the unit has after its revived
But i can see uppoints of your system:
original
special effects
easy configurable
hashtables
For voting, i give: 4.5 (Since there's no 4.5, i voted 4)
Thanks, it was useful for me
