She’s medium to short range so you gotta be close to do any real damage. Defense matrix doesn’t last very long so don’t hold it and use it all if it’s not used to eat an ult. Focus snipers/long range characters from picking off your back line/ support. Your boost does damage on impact so chasing down an enemy that’s almost dead and hitting them will most likely finish them off. Your ult can be used to help zone (clear a point) so don’t think it always has to be used for kills.
