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...
I think few players can kill 7* and full gear/skill Ray in the arena, so that we will have a permanent leader there, because all you need to Ray, this is fatty tanks couple, including imperial guardsman... And if Ray is your only chance in the raids, I'm sorry, it mean that your chars sucks lol And, and if your team survives in the arena, largely due to the fact that no one can kill your Ray, this too sucks.
