Jumping backwards off pipes and stuff

[CurdyMilk]

Overall, I like this idea.  In addition to pipes, it could be used for ladders, fences, and ledges where there is room below for the feet to kick off.  If the spy is hanging then obviously it can't work.  It would have to be balanced right because spies should still be more vulnerable to mercs when on these things.  Spies should not have a tactical advantage, but at least there is a little more option.
