We all know getting shot in the back is almost sure death as you come to a crawl so I've seen players jump to avoid the line of fire and it actually saves them quite a lot of times! It gets annoying because it's just stupid to look, reminds me of the days of Counter-strike. lol.
So I dunno, maybe this should be tweaked a little? I don't want everybody jumping around trying to avoid the line of fire considering the jumps are pretty high so it is kinda effective to jump.
Oh well..
