I disagree.
Having fighter torsos easily obtainable allows players to use them more freely (same concept as with anger weapons). We want players to use these unique items without being afraid of losing them. Furthermore, fighter torsos were never very difficult to obtain; giant champions dropped them quite frequently. So frequently, in fact, that people often wouldn't bother picking them up while training on giant champions.
Also, you can get over 4k tokens/hour using the catapult room, so decreasing the tokens dropped by animated armour wouldn't change the rate of tokens/hour too drastically.
