if someone wants to farm the jump skill over and over, it's his choice, making it even easier for him isn't a solution...PS: I've heard that there is a system which prevents you from getting high lvl platinum parts while repeating the same skill challenge or skill challenge type, nothing official, but some people noticed that when they switched the zone and challenge type, they were getting higher lvl parts more often... maybe a luck, maybe not... think about it while grinding your jump skill for years...
