i cant really say anything about people going for just the cape, me personally im going for 2 of the hardest capes to get(well most time consuming next to fishing) and that Slayer and Strength/Attack not because i want the skillcape but because i see alot of advantages in it and i love to train more than i do skill..plus on that fact slayer has alot of bonuses like the Abby Demons and Dark Beasts which drops items that are worth alot
