4 runs gave me 0 gold chests consequently while snatched boss for 8-9 times and used anzu, once.

To sum up, dmm veterans were right, snatch and anzu aint worth, go for d'art if you want her OPOP debuff, only! Otherwise she's as worse as Solomon. Actually, you still can use anzu to bait people who still believes anzu increase drop rates and use your anzu, thus get you more gems.
