Testing has shown that with random spawning of conserves and hives, the number of hiding spots on the native resource point starts to play a very significant role, along with double-builds. That is, if you can usually overcome such a situation with angels and ducks, it becomes much more difficult to do so with diverse troops. Therefore, the current idea is to allow players to order the type of spawn for a fee, with a progressively increasing price for repeats (to make it unprofitable to order 5-10 conserves of the same race). And also to make it less easy to obtain troops. But we haven't gotten around to implementing it yet.
