in casting buffs, they usually cast it on the largest number of units, maybe the largest number of HP.
Mist warriors wouldn't have done all that much good, as any penetrating hit from the sacreds' F9 fire attack would have dispelled it. would have slowed down the carnage a bit though.
OTOH, my guy didn't cast will of the fates - he must have blown an extra pearl on something else
it was an epic battle, and amazing how that bastard earth king got paralyzed and crippled at just the right times so that he held the field.
As to surrounding... yah, that was a bit of an error on your part - you should have patrolled your castle w/ your titan or the earth king - however, few of your troops actually ran off, so it didn't cost you as much as it could have.
