I feel the way an attack is absorbed is extremely flawed? I have 3.1m spy defense with 1m static. So if attacked by someone with 700k spy attack, why does game use 1 of each def pot especially when attacker uses no attack pots? I believe attack should be absorbed by sd 1st, then your stats and bfe/bfa, with pots coming last. That way a much weaker attacker can't burn your pots so easily when unnecessary!
def/spy def (including towers), banner bonus, bfa, pots - in this order game mechs works. So yes - even 700k sa will burn and if spells up and full pots it will get succesfully trough as well. Explained in Wulfs thread about buildings and lands
