Clans war _ clans allianz

Hello ! :) I have a sugestion, why clans don ´t do allianz? Well i wish this can help to all , the clans can do allianz then they took a donate gold , elixir... (not gems) can cooperate and then they can ´t do war between them.The clans allianz if they like can be for clans vs. clans and if that is. we will join very much.

Thanks !!
