So, consider this scenario: It's another day in the battlefield and you're a mighty warrior, bashing puny Spanish with your mighty club and fending off all attacks with your shield, and then, the cowards decide to hide behind a wall. What do you do, do you walk around the wall? HELL NO! YOU MAKE SOME STAIRS AND GET ON TOP OF IT THEN SMASH THEM WITH ARROWS FROM ABOVE! That's right, with the Bow you can stick arrows into walls to create stairs to help both you and your teammates get to areas faster.
