If it were two Warriors cooperating to get a treasure, the scene wouldn't be as glamorous as the scene of a group of Bandits getting a treasure. There would be no split-seconds appearances at different places or various illusions happening one after the other. At most, it would just be one Warrior shouting 'Hey b*stard' to lure the aggro of the monsters and the other Warrior shouting 'Son, I will tank the damage for you!' that kind of brotherly-love scenes…
It was fortunate that both of them were of different jobs, and hence the whole process of getting the treasures appeared somewhat more dashing.
