has anyone found any real use for armageddon

[clinek]

Ok, in KB:TL, armageddon had a really important role in one battle but in AP, i simply have not found any use for it. When fighting haas, you just armageddon has forces for the first two spells, then use the grim reaper to use time back on your unit and you have the battle won. If anyone found a real use for armageddon in AP please let me know. It just seems like one of those useless spells at this point.
