Ok, I observed a little what I get and this is what my conclusion to my other posts are. I get from expert about 8 or maybe 11 chest max (once got 3 chests, 3!!!! from expert map), from standards, i get around 8-9 chests. But for the last 3 times, I got a heart from standard, while from expert in 11 rows, I didnt get none. So there it is, standard is for me..... and btw about that weapon chance drop..... let me just say, if I already get less chests that is normal, I dont get any hearts from the expert map, how big chance is for me to even get that freakish SSR weapon you posted.... let us just say almost zero....
