I use all my jumps in p1..when she moves away for chariot you can jump over..finish your combo and jump back (ssd will be up for the 2nd chariot so with dfd on cooldown you can use EJ).

How are you losing time running to the boss at the start..if you run with your tank you start hitting as soon as he pulls..its useful yeah if you were half asleep and your tank has run off and you need to get there fast but I wouldn't use it as a staple starting move
