Increase the new modifier's limits (perhaps other ones).

JumpHeight's limits are 0.5 to 2,
ThrowForce's limits are 0.5 to 2,
ClimbingSpeed's limits are 0.5 to 2,

I don't really see the point of having these "restrictive" limits, yes, any values above or below would be completely unviable in most cases, though Map Makers would be able to create funnier restrictive gimmicks with a wider range of these modifiers. MeleeForceModifier is 0 to 10, so why have these capped at 0.5 to 2?
