I understand what you're saying but in my opinion it shouldn't take one spell (even if it's upgraded) to completely kill a bunch of troops, as I think that eliminates strategy.
I also see what you're saying about it only taking two spells to destroy high hitpoint troops - I have changed it to smaller damage increments depending on level, but making it do 3x damage to weak troops.
Thanks :) I honestly think this would be a great addition to the game. Of course, why wouldn't I, I suggested it :smirk:
