A reupload from ponibooru.  
It was during the time when I still didn’t understand how does defeating the leader of a group automatically makes you win a huge battle, especially if all enemies are just as capable as the leader. The only way that makes sense to me is if the leader was absurdly more powerful than the weaker soldiers and without them their overall strength should dimenish greatly.
 
I’ve learned from the many bronies that made their replied to it back in ponibooru that it was due to the combination of lack of coordination and imitidation of their leader’s defeat that the other side has a greater chance of winning. Though in this situation, if our heores did manage to beat Chrysalis here and there, would it really change the tide of battle so quickly?
