Jumps being used tactically to take less damage and jump over things on the ground so I can get to the group faster and not take the long way around. Also a little bit of bunny hopping at the start to infuriate the morons that get angry at that. lol

I've yet to hear a single argument that can say that its not a good gameplay element when done correctly and given a purpose. Instead of jumping for the sake of jumping.
