That is defiantly not how the circles in WoD work. You either need an even or odd number of players in the circle to prevent all effects. The killing people with a moving circle is admittedly fun though.
Elusive jump is very useful after you get the hang of it, more notably the distance it covers.
Sheds half your hate so in long fights its more effective at this the longer you go before using it.
Its good for gap closers as it moves you at sprint speed without the tp loss, my suggested use is recovering to a mobs you had to run out of an aoe from, using it to dodge out of them is not advised unless you are really really good at it for the above mentioned movement calculation. Or chain it with spineshatter/dfd and you have the largest gap closer combo in the game.
