I have not enough honor to buy Royal Archives design; however I do not think reset honor is good.
Firstly people would buy and reset all the time, I know one crafted 6 claymore items, he would not need claymore design anymore, if reset he would craft all item with only 20k honor, i.e. honor point has no meaning at all.
Secondly, when you tap BUY, with limited resources (even in your real life, buy with limited money), you have to use your brain with your action. Let say you bought Galaxy Note 8, use in 3 days then reset (get full money back), buy iPhone 8 use 3 days and reset, ... I would say human kind grows better without such people <- my last words in this topic.
