Doesn't hurt to make rare treasures for all modes, doesn't have to be co-op exclusive, but yea I agree we need another weekend already.
I only need 1 treasure in the whole game and I'm done... I got all character guns, every single stat hat, and all I'm missing is 1 treasure just ONE for skelzor.
If it is like the other weekends, then rare treasures are pretty frequent, if it is a mode with a lot of rare treasures though (i.e co-op arena) you will possibly get tons of duplicate rare treasures if you have most of them and it will still take some time before you get the one you want.
F-it. Won't buy another dlc. Maybe I'll play FFA again. But I don't really need Chloe's m9.....
