broodlords do full damage to thor, plus they create broodlings, thor do half damage to broodlords, due to broodlord consider as armored unit, and in a fair fight, ie 3 broodlords vs 3 thors(1v1 or 2v2), broodlords will always win with outstanding result, only with 1 exception, many broodlords vs many thors and all broodlords are stack together, cause thor can do area damage, if they split out, broodlords will win. default damage for thor vs broodlord should be 6 minus off the armor of broodlord, which left 5 per attack, and broodlord do 20 minus off armor which means 19 per attack plus broodlings. if broodlings didnt get killed(concentrate fire on broodlords), they can do like 10-12 extra attack b4 it dies which is 4(?) damage per attack.

like what i said, in a fair fight =P, i think he did lose quite a number of scv 2 killed by broodlings ?
