Your suggestion will never get implemented bcos COTK follow their Chinese counterpart business model thinking that many people in English server rc like those in Chinese server for food.
The biggest issue here in English server is the rc amount of gold is 3 times less than those in Chinese. In Chinese, if you rc USD100 you get 6600 gold for example instead of the miserable 2300 gold you will get here. Plus the US exchange rate have gone up therefore Itunes/googleplay have adjusted the $$ higher for rc.
Chinese server still have the same amount of killing & feat chest as English as of now & also facing food issue like us but their way of getting more food is to use gold buy from Limited pack or from Wishing Well event & they can afford to use gold to buy becos the rc bring you 3 times more gold than in here therefore those playing in Chinese are more willing to rc to spend on food.
Conclusion is the food issue will never get solve in COTK. Save your effort.
