The chest, like any other wonderful thing lying on the ground, should not be taken diagonally, and you shouldn't even move the character who is taking this item diagonally!
Resources CAN and SHOULD be taken diagonally; it's just important to know when it's beneficial. By the way, this is a clear example of a post that doesn't carry any meaningful content but expresses a desire to kick someone who is already being attacked (just to join in, perhaps?). Turn management is an important part of the game; I think even Neverminder understands this, but for some reason, I'm sure that after all the posts about "taking chests diagonally," he won't have any desire to read articles about how to move units rationally. One wise man said: "No one can teach another person anything." A person learns on their own; you can't force knowledge into them, but you can discourage them from wanting to learn (maybe this is the goal of the authors?).
I miss the old World, when there was a real Community of people united by one game. They shared what they could, rejoiced together, and now, everywhere you look, there's no getting away from arguments; they constantly bite each other over trivial things that sometimes aren't even worth mentioning...
