During DOTM it is stated byLennox (I think it was Lennox) that the Transformer's weak spots are the eyes. Clearly because it blinds them (i.e Starscream) So far so good. But I believe that the Transformers have some sort of a soft/weak spot in their shoulders. Notice how in almost every majoor battle (Forest, desert, Chicago) at least one character had a sword/any other weapon stuck in their shoulders? During the forest battle, Optimus stuck his sword into Megatron's arm. I'm pretty sure it happened during the desert battle too, but I haven't watched ROTF in a while so... During the legendary Chicago battle in DOTM, Sentinel sticks his sword in OP's shoulder, therefore removing his arm, later in the battle, Optimus sticks his axe into Sentinel's shoulder. Do you think the actual perpouse of this method os just to remove the enemy's arms, leaving them defenceless, or an actual weak spot to inflict pain?
