I think most people would agree here that point&click damage abilities and spells needs some looking at. It's really lame that one can just overcast an easily applied single Fate of Bjuna and practically delete an expensive elite unit from the game with no cost but WoM, which is in most cases is a way to effective trade for the caster.
So I think there needs to be some sort of balancing element beyond just increased WoM cost. Here are some ideas:
1.Increase the miscast chance for overcast P&C damage spells, if at least for the stronger ones
2.Slow/root the caster while the spell is in effect, that way "sniping" becomes more of a risk
3.Reduce armor/MD of the caster while the spell is in effect, same as above
4.Make those spells more expensive to equip
I think a combination of at least some the points is in order because P&C damage abilties/spells are cancerous to balance as long as we aren't getting a counter-spell system, which won't be arriving until WH3 if at all I'm afraid.
