Drop Cham and sadow. (Diablo 2)

Recently discussed ideas for reducing the cost of zod as a key item, but it is too much impact on the current economy.
I suggest a good alternative. It is necessary to reduce the chance of drop Cham and zod. In recent years they too often fall, in consequence of which and uber Diablo appears quite often, and anyhow per capita becomes too much, thus they are worthless.
I think if you reduce the drop chance of runes in the above 3-4 times, be quite good for the current situation on the server. When people were namogo more anyhow not enough, but now the little people and Anichi not particularly necessary, so you need to keep their value.

Well, in the end, it fits perfectly into a server policy, NO SIMPLIFICATION!
