The petard and the flaming camel, are self-destructs units,the petard(cost: 65 food, 20 gold), the flaming camel (cost: 75 food, 30 gold). My discussion here is about reducing the food cost and maybe the gold too-if it possible. Maybe some of you will said “Well ok, no one use them anyway that much!!!”. Well for me they can be very useful if you know how to use them!!! But the cost 65 or 75 food for a self-destructs unit is really not cheap because of course you will prefer put this food on light cavs or other trash units rather than this!!! So my suggistion for this is:
-reducing the food cost by (-20), so the petard become 35 food and the flaming camel become 55 food.
-reducing the gold by (-10) so the petard become 10 gold and the camel 20 gold.
-make the flaming camel available in the castle age without a unique tech
With this cheap cost, i think it will be more useful to use and motivates the players to use them more in the battles.
