Bring back the old research tree for the World At War map

In my opinion, The World at War map should take long. Especially since it takes A WEEK to get from Australia to France. So just bring back the old research tree that takes longer for the World at War map, the old research tree was actually better in my opinion, since it made you think about what to research first instead of researching everything at once. And nukes weren't available at day 14.
