Why are Nightmare raids supposed to be difficult
From what I have seen others get from chests and what I got from them as well, the buff to the rewards don't seem anything significant. The exploration rewards are nice but nothing amazing. Tier 4 alpha and 7 stars are more available nowadays.
So my question is why are nightmare raids supposed to be some difficult piece of content to complete when they offer only marginally better rewards. I don't think anyone was asking for a new difficulty for raids. The base raids could gotten the buffed rewards and it would have been better overall.
