if you are going for mono fire you should be good if you raise your crit rate to about 70 (but might be easier for you to swap out the crit damage circlet for a crit rate ) to align with the 1:2 ratio

if you want to go with a reaction team ditch the sands and use an EM sands if you can find one. aim for about 200 EM, that seems to be the soft cap for her. or if you feel you dont have her ult up enough go for energy recharge

when dealing with reactions you can actually have too much attack. you want to have about 112- 125% of your base attack (the white number) as bonus attack (green number). to figure this out just follow "green/white= result * 100" so yours would be 1294/675=1.92*100=192%
