Grats, I'm still grinding with my Ayana Kwena in non spawn mode, but I have max TH/BH so I get drops a fair amount of times anyways. But I can't stay there too long or my MMR goes down too low and then I'm grouped with baby herecs and lowbies, and that's REAL bad.
You should record some gameplay with it. It looks like an awesome weapon.
EDIT: I watched the video. Quite a thrashing. At the very end I vicariously felt the extreme relief and satisfaction when you highlighted the blueprint and it was Shy. It got me stoked to grind tonight.
