On assist she should not be able to proc foresight off of her basic attack. I just played a game where she never dropped foresight the entire match because of assists and phasma leader skill, even...
Those people who are crying to nerf Rey... please go fight a lvl 80 gear 8 or better Sun Fac and then see if you still want to nerf Rey! I guarantee you will be coming back shouting to nerf Sun Fac and leave Rey well well alone.
Even if you don't want to do that... go do a Tier 6 or higher raid and then come back
Chances are if you do either of the above, unless you are absolutely mad or just plain trolling, you will not be crying to nerf her.
