badlands : unbalanced map ?

[SilverKronos]

so i just tested badland in sandbox and it finds out that it's a unbalanced map aswell. top player is disadvantaged because of the two plateau on left and right.
bottom player can detroy two mex of top player by building mml on these plateau, but top player can't destroy anything of the bottom player with this tactic.

it's a little unbalanced :s maybe someone can replace these plateau correctly ?
