A couple of more things, now about your ww-base. Again, putting all of your traps on one side is not a good idea, there’s a big chance that attacker will choose the other way (for example, I never attack from Versailles, I don’t like my army moving slowly). And your caltrops: they don’t stack, so putting two caltrops together means that you’re wasting one of them, if you want to use them together then make it a chessboard, this way you will maximize the area of their effect. Actually, caltrops are one of the most effective defensive constructions, far more effective than mortars, towers or anti tank/air guns, yours are two low in level for atomic base, you should really reconsider your upgrade plan and give them more priority)
And one more thing: one square at the bottom of the map doesn’t have gates for exit, so if I put a decoy in that square, your defenders in that area will be completely switched off from the attack, standing around and trying to figure out the shortest way to that decoy.
