Yes there are different points and different situations to consider..You have to go with what works for you and the situation..Its more or less about taking the walls down without wasting the expensive troops, which will be needed for the main army. We all know that the walls in conjunction with a meager army can be strong. and sending in rainbows and other troops as bombs focus on the main troops and not the outer defenses. once the outer defenses are gone, then inside those large amount of troops are much weaker. but then again, worked for our alliance...use what you think works..just trying to help someone out there. any advise is better than no advise...happy plundering........
