I tend to agree. In Revised the main reason to stack Bury was to take pressure off Borneo and Pearl, while simultaneously threatening Manchuria or the distracting the rest of the mainland. Here Pearl is a non-issue, there are less units to stack into Bury, the transit to East Indies takes longer even if USA goes south, and its easier for Japan to push the center or India out of sz 61. That said, if you were going to leave units behind in Bury, the only reason to do so is to hold the battleship and transport north in the first round, which you can probably accomplish just leaving 1 inf behind. Putting 5 into it, just seems like throwing the ipcs away. Stacking Yakut, or pushing down to hold the center, is likely more advantageous than stacking Buryatia on this board.
