It's not about making it easier. Just less frustrating. The long leash distance does not make mozja enemies difficult or dangerous. Just frustrating. They're still trivial outdoor mobs in the way of the content people are trying to do. If they were actually dangerous, like say the sleeping dragons in Eureka, that'd be one thing. But they aren't, with the exception of the 'rare mob' guys you see now and then. They just waste time.
