To up the cost of a mystery chest from 175 to 250 is too much, you should have buffed every other chest instead to make it ok to go for them instead of the mystery chest. It is no fun to farm 350 cinders to open 2 mystery chests, 500 is just dumb, especially when you already need to be highly geared to quickly farm cinders. I do not want to play a game that feels like a job after I have come home from my real job, do you not understand that???
There is an issue with Cinder drops right now.
Some mobs drop what they were.
Others drop 1.
I think once they fix that it will be a little better.
I used to get like both mystery chests and about 3 other random ones during a Helltide before.
Just did the last one and got one mystery chest and one other.
Big difference.
