Basically I got one on t7 when I was first leveling up my delve to tier 8 and ever since I have done at least 15 bountiful delves and some non boutiful t8’s and still not a single drop on t8. Why is up with the droprate? Apparently you can drop up to 3 a week but feels like the droprate is just way too low.
I know the hero grade item is kind of big reward for it to be easy to get 3 weekly but how many runs should you get them from? 50-100? No way people are going to farm it without keys. Basically nobody runs delves if they don’t have keys.
Perhaps cap it down to 1 or 2 weekly but buff the droprate so you are going to get the 2 for sure within reasonable runs.
