Now I got the document for new / old item prices. And what I see is changes seem good. Price of expensive items for high tier troops are generally reduced by 4-5x even some are 10x while low tier ones are usually similar :
Formula is still same by the way and which troop has which item data will not change. So you will get 440 value of expected loot from a killed tier-5 troop same as older versions. However it will make more sense with new reduced values and you will get see loot dropped from high tier troops after battles. I will try to make this formula 20x for nobles. So a level 26 lord will give 20x more expected loot which is about 9K. So you will get about 5-10% chance of getting his 50K item. (Even still leaving 50K item at battlefield not realistic it is better than 0.1%)
