Hi, LordStark! Yes, an attack by commandos can please for the time being.. but at WW, a Ground attack against lvl 300+ with an adv Museum, shields, etc. won't get you 100% destruction on time.. Even if you have enough attack power, you just won't make it. Now this is solved only by air bombing.. the balance of troops is still not there..and the time limit exacerbates this imbalance which leads everyone to the only winning tactic..
